Curation notes
--------------

Identity checked against the first page \(PDF page 1, journal p\. 263\)\: Malicet, Daumont, Charbonnier, Parisse, Chakir and Brion, J\. Atmos\. Chem\. 21, 263\-273 \(1995\), 'Ozone UV Spectroscopy\. II'\. Journal pages 263\-273 = PDF pages 1\-11\. O3 only\.

Facts for the data files \(the Brion/Daumont/Malicet 'BDM' temperature set\)\: \- Temperatures\: 295, 273, 243, 228 and 218 K; 195\-345 nm, except 273 K, 300\-345 nm only \(p\. 272\)\. The 295 K spectrum is daumont\_1992's; the low\-temperature ones were first reported by Brion et al\. \(1992, 1993\: brion\_1993\) \(p\. 266\)\. \- Resolution\: 'Spectral bandwidth Delta lambda = 0\.01\-0\.02 nm' \(Table I\); 'determined under high resolution' \(abstract\)\. Sampling not restated here \(daumont\_1992\: 0\.01 nm steps\)\. \- Wavelengths\: the medium is not stated in this paper; the method and calibration are daumont\_1992's, 'in air' \(recorded as standard air\)\. Wavelength uncertainty 0\.005\-0\.015 nm \(Table II; the HR 640 is 'slightly less precise in wavelength than the THR 1500', p\. 265\)\. \- Absolute scale\: the pressure method \(Eq\. 1\), not normalised; at 253\.65 nm compared with Barnes and Mauersberger \(Table III\: \-0\.26 to \-0\.48 %\)\. \- Uncertainty \(Table II, image checked, p\. 266\)\: absorbance 1 %, optical path 0\.05 %, ozone pressure 0\.1 %, temperature 0\.02\-0\.15 %, impurities \< 0\.1 %, wavelength 0\.005\-0\.015 nm; total systematic error 1\.3\-1\.5 % \(Hartley band\) and 1\.3\-3\.5 % \(Huggins band\); random errors \(RMS\) 0\.3\-2\.0 % \(lambda \< 340 nm\)\. Level not stated\. 'the standard deviation calculated with 10 scans stays underneath total error estimations' \(p\. 265\)\. \- The published file\: 'All these data have been gathered together on a floppy disk, available on request' \(p\. 267\); the paper prints no spectrum \(Figs\. 2\-4 only\)\.

Temperature dependence \(pp\. 267\-270\)\: weak in the Hartley band \(at 253\.6 nm the cross section decreases by 1\.0 % from 218 to 295 K; 1\.15 % by the dew\-point method of Malicet et al\. 1989; 0\.8 % Molina and Molina\); none in the 210 nm window; strong in the Huggins bands \(more than 50 % towards long wavelengths; sigma\_218/sigma\_295 about 0\.4 in the minima and 0\.9 at the band tops\), with a red shift of the structure below 0\.06 nm from 218 to 295 K\. Parametrisation \(p\. 269\)\: sigma = C0 \+ C1 theta \+ C2 theta^2, theta the temperature in C, fitted per wavelength \('a 4\-coefficient polynomial making no significant improvement'\); the coefficients are not printed \(not a formula entry\)\.

Comparisons \(p\. 271\)\: Molina and Molina \(226 K\) within 1 % below 240 nm, 1\.5\-3 % higher above; Yoshino et al\. \(1993\) 0\-5 % too low below 254 nm; Bass and Paur within 1\.5 % in the Hartley band at 298, 243, 228 and 218 K, but their Huggins structure shifted by \+0\.05 nm \(and \-0\.1 nm more at 218 K in 313\-318 nm\); Cacciani et al\. \(339\-345 nm\) agree in the mean, with shallower band contrast\.

Datasets\: Tables III and IV \(images checked\), in 10^\-19 cm^2 \(headers 'sigma x 10^19 cm^2'\); scale 1e\-19 to cm^2\. This work's values are points of the BDM spectra\: 'check' \(the checks on the data files\)\. Each temperature is its own dataset \(a dataset has one temperature\)\. The relative\-difference columns are derived and not extracted\.
