### Numerical representation of the results

Numerical files are displayed in View tabs and downloaded to a user's computer contain several header lines starting with " # " character, which give a verbal description of the contents of the file and the parameter values of the simulated spectrum. Below are the data columns.

The file of

*partition functions*consists of two columns: the first one contains the temperature

*in*

**T***K*, and the second is the value of partition function

*for this temperature. The format of the data line in Fortran notation is "I4,3X,F20.6".*

**Q**Files of experimental

*absorption cross-sections*, as well as files of t

*ransmittance, absorption*and

*radiance*spectral functions also consist of two columns, the first of which contains the value of the wavenumber

*in*

**WN***cm*, and the second the value of the corresponding spectral function for this wavenumber. The format of the data line in Fortran notation is "F12.6,3X,E17.10".

^{-1}The file of calculated

*absorption coefficients*contains three columns. The first column contains the value of the wavenumber

**in**

*WN**cm*, the second value of

^{-1}*[cm*

**KN**_{a}^{-1}], and the third is the value of

*in*

**K**_{a}*cm*for this wavenumber. The format of the data line in Fortran notation is "F12.6,3X,E17.10,3X,E17.10".

^{2}/moleculeThe file of calculated

*absorption cross-section*also contains three columns. The first column contains the value of the wavenumber

**in**

*WN**cm*, the second value of

^{-1}*in*

**XS***cm*, and the third the

^{2}/molecule*absorbance*

*in*

**A***ppm*for this wavenumber.

^{-1}·m^{-1}For

*list of spectral lines*file two formats are supported: HITRAN-2004 and SPECTRA. The first one completely coincides with the 160-character format, described on p. 142 in [1], the second one is the traditional format of the

**system.**
