Bases: DatabaseManager

get_linereturn_format(opener, urlname, columns)[source]
keep_only_relevant(inputfiles, wavenum_min=None, wavenum_max=None, verbose=True) list[source]

For CO2 and H2O, return only relevant files for given wavenumber range.

If other molecule, return the file anyway. see radis.api.hitempapi.keep_only_relevant()

parse_to_local_file(opener, urlname, local_file, pbar_active=True, pbar_t0=0, pbar_Ntot_estimate_factor=None, pbar_Nlines_already=0, pbar_last=True)[source]

Uncompress urlname into local_file. Also add metadata

  • opener (an opener with an .open() command)

  • gfile (file handler. Filename: for info)


register in ~/radis.json


Get non-empty lines of a chunk b, parsing the bytes.

keep_only_relevant(inputfiles, wavenum_min=None, wavenum_max=None, verbose=True) list | float[source]

Parser file names for wavenum_format (min and max) and only keep relevant files if the requested range is [wavenum_min, wavenum_max]


  • relevant (list of relevant files)

  • files_wmin, files_wmax ((float, float) : wavenum min & max of relevant range)
