IDENTITY AND LIBRARY\. original/source\_01 \(Cover\-2\.pdf, 28 pdf pages\) is the front matter\: title pages \(pdf pp\. 1\-2\), acknowledgements, preface, the introduction \(Definitions; Methods of Measurement and Errors; Use and Misuse of the Data; pdf pp\. 5\-24\), its 67 references \(pdf pp\. 25\-27\) and Table 1, the abbreviations \(pdf p\. 28\)\. source\_02 Ag\.pdf \(11 pages ending with the table on book pp\. 52\-53; supplement\_01\), source\_03 Al\.pdf \(pp\. 70\-86; supplement\_02\), source\_04 Au\.pdf \(pp\. 54\-69; supplement\_03\), source\_05 Bibliography\-2\.pdf \(pp\. 239\-256; supplement\_04, text only\)\. The copper chapter is not in the library \(J\. C\. Travers's scan, pp\. 32\-42, is described below\)\. The citation is the library's asserted BibTeX \(no DOI; ISSN 0344\-8401 and 'Nr\. 18 \- 2', 1981, from pdf p\. 1\)\. Page numbers below are the book's printed page numbers \('\-79\-'\)\.

WHAT THE INTRODUCTION SAYS \(source\_01 pdf pages\)\. Range 25 A \<= lambda \<= 25 um, ~0\.05 \<= hv \<= 500 eV, hv \(eV\) = 12398/lambda \(A\) \(pdf p\. 5\)\. Convention exp\(\-i omega t\), epsilon = epsilon\_1 \+ i epsilon\_2, N = n \+ ik = sqrt\(epsilon\), epsilon\_1 = n^2 \- k^2, epsilon\_2 = 2nk, R = \(\(n \- 1\)^2 \+ k^2\)/\(\(n \+ 1\)^2 \+ k^2\) at normal incidence, mu = 4 pi k / lambda, loss function Im\(\-1/epsilon\) = epsilon\_2/\(epsilon\_1^2 \+ epsilon\_2^2\) \(pdf pp\. 8, 13\-14\)\. Kramers\-Kronig of the reflectance\: 'the extrapolation errors affect the magnitude of epsilon\_1 and epsilon\_2 much more than they affect the positions and shapes of spectral structures'; for Mo their dispersion\-integral results over 0\.1\-30 eV agree with photometric and ellipsometric data 'to within 10%, while an error analysis yields an estimate of possible errors of up to 50%' \(pdf p\. 17\)\. Electropolishing leaves 'a smooth, strain\-free surface, but one with an overlayer of oxide', which 'causes little error in the infrared reflectance, but above about 6 eV the 2p electrons of oxygen absorb and cause errors' \(pdf p\. 20\)\. The tabulated data 'were measured with bulk samples' and are less suitable than film data for modelling evaporated films \(pdf p\. 21\)\. UNCERTAINTY\: 'We believe that the data tabulated are good to within \+\-10% in most cases \(except near places where epsilon\_1 crosses zero, for which a relative error is meaningless\)' \(pdf p\. 22\), recorded as relative 0\.10, level not stated, on the n and k datasets of both metals\. The anomalous skin effect was ignored in obtaining epsilon \(pdf p\. 23\)\. 'We have presented room temperature or liquid helium temperature data only' \(pdf p\. 23\)\.

ALUMINIUM TABLE \(pp\. 79\-86; datasets n\_Al, k\_Al primary, eps1\_Al, eps2\_Al check\)\. Supplement\_02 tables tbl\_41f659cbf54e \(p\. 79\), tbl\_41f03578c473 \(80\), tbl\_550bc2056f85 \(81\), tbl\_6b7f728e7af0 \(82\), tbl\_5937497d4313 \(83\), tbl\_7ae05093ee33 \(84\), tbl\_b1243e5e0609 \(85\), tbl\_bd839bc39e50 \(86\)\: the page order is the pdf order, each page continuing the last \(0\.190/0\.195, 1\.460/1\.480, 14\.400/14\.500, 25\.500/26\.000, 72\.400/72\.500, 111\.000/112\.000, 340\.000/350\.000 eV\)\. 447 rows, 0\.040\-1551\.000 eV, energies as printed \(1049\.999, 1099\.999 \.\.\.; 0\.002 eV steps at 0\.04\-0\.1 eV growing to 0\.05 eV at 0\.6\-1\.2 eV, 0\.02 eV over the 1\.5 eV interband peak, 0\.05 eV at 14\.5\-16 eV around the plasma edge, 0\.1 eV at 72\-74 eV at the L edge, 10\-50 eV above 200 eV and 1\-2 eV again at 1540\-1551 eV\), E, epsilon\_1, epsilon\_2, n, k, Im\(\-1/epsilon\) to three decimals and R to four; the loss function and R are kept in printed\. Each page was compared with its image\. PROVENANCE\: the book is where this tabulation was first printed\: shiles\_1980 \(the analysis\) says its full tabulation 'will be given elsewhere', citing Ref\. 12, 'E\. Shiles and D\. Y\. Smith \(unpublished\)'; so the datasets are this record's, with no reproduced\_from, and shiles\_1980 is the analysis \(compiled reflectance, ellipsometry and absorption data joined by Kramers\-Kronig and sum\-rule tests, with kappa above the L edge reduced ad hoc by 14 % to satisfy the f\-sum rule\: see that record\)\. ordal\_1983's Shiles block is a reproduction of this table \(reproduced\_from shiles\_1980 and this record\); rakic\_1995 took Shiles et al\.'s k above 14\.9 eV through Palik's Handbook \(Smith, Shiles and Inokuti\), which is why it agrees with this table from ~35 eV\. CHECKS \(2026\-09\-28\)\: in every row epsilon = N^2 holds within the bound set by the printed rounding \(worst 0\.97 of it, 0\.650 eV\), Im\(\-1/epsilon\) from epsilon within its bound \(worst 0\.99, 1\.280 eV\) and R from N within 0\.0016 \(all within the bound\) once three library misreadings are fixed in the script against the images \(1\.700 eV R \.8977 for \.8972; 27\.000 eV epsilon\_1 0\.700 for 0\.706; 134\.000 eV Im\(\-1/epsilon\) 0\.036 for 0\.038\), and one misprint is corrected by erratum \(17\.500 eV k printed 0\.036 for 0\.038\)\. k = 0\.000\: from 500 eV k prints 0\.000 in all 47 rows \(500\-1551 eV; and epsilon\_2 0\.000 from 600 eV, Im\(\-1/epsilon\) 0\.000 from 600 eV\)\: kept as printed, but these rows carry no absorption information \(k \< 0\.0005 only; k = 0 cannot be used for an absorbing model\)\: the range is cut at review\. Above ~350 eV n also rounds to 0\.996\-1\.000 \(delta = 1 \- n to one or two figures only\)\.

ALUMINIUM COMPARISONS \(2026\-09\-28; interpolated in this table\)\. ordal\_1983's Shiles block \(26 points, 323\-16100 cm\-1, 0\.040\-2\.0 eV, three figures\)\: n within 0\.85 % and k within 0\.41 % \(medians 0\.01 % and 0\.05 %\), its rounding\: a faithful copy\. ordal\_1988 \(40 points, 0\.043\-1\.86 eV, their own Kramers\-Kronig with the cavity data, which uses Shiles et al\. above 320 cm\-1\)\: n 2\.1 % higher \(median; up to 3\.0 % at 1\.61 eV\), k 1\.1 % higher \(up to 1\.35 %\); e\.g\. 1\.0 eV 1\.233 \+ 12\.61i against 1\.212 \+ 12\.46i\. rakic\_1995 \(film data to 14\.9 eV, Shiles et al\.'s k above\)\: 0\.05 eV 68\.5 \+ 164\.8i against 75\.0 \+ 172\.2i \(n \-9 %, k \-4 %\), 1\.0 eV 1\.316 \+ 12\.24i against 1\.212 \+ 12\.46i, 2\.0 eV 1\.366 \+ 7\.405i against 1\.304 \+ 7\.479i, 5\-10 eV within 1\-5 % in k, at the plasma edge \(15 eV\) n 0\.151 against 0\.125 and k 0\.110 against 0\.153, from ~35 eV the same to this table's three decimals\. mcpeak\_2015's film \(200\-1700 nm\) against this table\: \|epsilon\| 21\-31 % smaller \(31 % at 200 nm, 24 % at 500 nm, 21\-22 % at 800\-1700 nm; 1550 nm\: \-197\.9 \+ 38\.1i against \-252\.6 \+ 46\.1i\)\.

GOLD TABLE \(pp\. 64\-69; datasets n\_Au, k\_Au primary, eps1\_Au, eps2\_Au check\)\. Supplement\_03 tables tbl\_e1aa4a8fd3ac \(p\. 64, 49 rows\), tbl\_0099904bfe57 \(65, 57\), tbl\_3b6da8494ea6 \(66, 57\), tbl\_c59b9057cc82 \(67, 57\), tbl\_22fe363af672 \(68, 57\), tbl\_e323eaae89b9 \(69, 7\), in page order\. 284 printed rows, 0\.10\-30\.00 eV \(0\.05 eV steps to 1 eV, 0\.1 eV to 2 eV, 0\.05 eV to 2\.3 eV, 0\.02\-0\.03 eV to 3 eV, 0\.05 eV to 5 eV, 0\.1 eV to 16 eV, 0\.2 eV to 30 eV\), E, epsilon\_1, epsilon\_2, n, k, Im\(\-1/epsilon\) to two decimals and R to three \(epsilon also two decimals when large, e\.g\. \-6794\.55 at 0\.10 eV\)\. The book is now the printed source, so its rows are the primary data \(n, k to two decimals\: at 1\-1\.7 eV n = 0\.13\-0\.08 carries only one or two figures; epsilon is the more precise there\)\. CHECKS \(2026\-09\-28\)\: the library's cells were compared one by one with an independent transcription of the page images \(made before the pages entered the library, from J\. C\. Travers's scans\)\: they agree except four library misreadings, fixed in the script against the images \(2\.20 eV R \.980 for \.880; 2\.50 eV epsilon\_1 \-1\.96 for \-1\.86; 19\.40 eV k 0\.76 for 0\.78; 28\.80 eV epsilon\_2 0\.65 for 0\.85\)\. Then epsilon = N^2 holds in every row within the printed rounding \(worst 0\.93 of the bound, 15\.50 eV\) and Im\(\-1/epsilon\) within its \(worst 0\.97, 1\.90 eV\)\. The printed R is not the R of the printed n, k\: from about 2\.7 eV up, \|\(N \- 1\)/\(N \+ 1\)\|^2 exceeds the printed R by up to 0\.0064 \(24\.20 eV\: \.119 against 0\.125\), and falls below it by up to 0\.0049 elsewhere; R is presumably the measured reflectance the analysis started from \(not stated\)\. THE BOOK'S MISPRINTS \(errata; register entries for review\)\: the energy after 6\.50 eV is printed '6\.50' again \(p\. 66; the sequence and the workbook have 6\.60; row id '6\.50 \(repeat\)'\), '26\.50' is printed for 26\.60 \(p\. 68\); the 8\.40 eV row is printed twice, identically \(p\. 66\)\: the repeat, row id '8\.40 \(repeat\)', is excluded\. So 283 rows are used\.

THE WORKBOOK'S COPY OF THE GOLD TABLE \(datasets sheet\_n\_Au, sheet\_k\_Au, sheet\_eps1\_Au, sheet\_eps2\_Au, all check\)\. J\. H\. Weaver's website workbook, the file behind babar\_2015 \(optical\-constantsCuAgAu\.xlsx, sheet 'JHW\-Au\-ZAED', fetched 2026\-09\-28 and attached to babar\_2015's paper in the library\)\: 217 rows, 0\.1\-30 eV, E \(eV\), R, n, k, e1, e2 \(no loss function\), on a grid of 0\.1 eV to 1 eV, 0\.2 eV to 2 eV, 0\.1 eV to 4\.4 eV, 0\.2 eV to 6 eV, 0\.1 eV to 16 eV and 0\.2 eV to 30 eV \(it leaves out 66 of the book's rows, all below 6 eV\)\. Its e1, e2 are the book's \(five figures where \|epsilon\| \>= 1000, e\.g\. \-6794\.6 for \-6794\.55\) and its n, k are sqrt\(e1 \+ i e2\) of them to five figures \(to 6\.4e\-5 relative\), not the book's two\-decimal n, k\. Against the book, now settled on the library's cells and the images\: the SHEET is wrong at 12\.2 eV \(e2 2\.02; the book 2\.03\), 17\.6 eV \(e1 0\.86, copying the 17\.8 eV row; the book 0\.85\) and 21\.4 eV \(e1 0\.23; the book 0\.27, which with the book's n = 1\.03, k = 0\.88 is consistent; the sheet's n, k there, 1\.0135, 0\.8929, are off by 1\.6 %\), and at 11\.4 eV \(R 0\.11 for the book's \.111\)\. No book erratum follows from them\: they are copying errors of Babar and Weaver's sheet\. Otherwise the sheet's n, k round to the book's except at 27 rows \(by at most 0\.0071\: the book's n, k were computed from unrounded epsilon\) and the book's loss function agrees with the sheet's epsilon but for rounding \(11 rows, 0\.009 or less\)\. The sheet's energies 6\.6 and 26\.6 confirm the two energy errata\. Against ordal\_1983's copy \(Table 3's Weaver block, 21 rows, 807\-16100 cm\-1, reproduced\_from this record\)\: the same to its three figures \(k within 0\.14 at 41\.7, 0\.3 %\)\.

GOLD\: SAMPLE, TEMPERATURE\. Electropolished Au\(110\) single crystal \(p\. 64 heading\), bulk\. The Au survey table \(p\. 57, 'Au\-4'\) lists 'We Unpl, 0\.26\-4\.2 eV, Refl, 4\.2 K, X\-tal, EP, A, absorptivity measured by calorimetry'; the bibliography \(p\. 255\) gives 'We Unpub\: J\.H\. Weaver, Unpublished'\. So the 0\.2\-4 eV part of the table MAY BE LIQUID\-HELIUM\-TEMPERATURE ABSORPTIVITY \(4\.2 K\), not room temperature\. The table's heading does not state a temperature, and 'OL Unpub' \(C\. G\. Olson and D\. W\. Lynch, ~4\-30 eV\) has neither a survey\-table entry nor a bibliography entry \(the bibliography has OL81, Olson and Lynch on rare\-earth trifluorides, not this\)\. parameters\.temperature\_k is therefore not set; this should be decided before using the table as room\-temperature gold below 4 eV \(babar\_2015 used this reflectance for its room\-temperature Au analysis, its Fig\. 3\)\. Figs\. 13\-15 \(pp\. 60\-62\: R, epsilon\_1, epsilon\_2 to 30 eV\) show 'We Unpub \(~0\.2\-4 eV\) and OL Unpub \(~4\-30 eV\)' as the solid line among the other authors' data\.
