class HITEMPDatabaseManager(name, molecule, local_databases, engine='default', verbose=True, chunksize=100000, parallel=True)

Bases: DatabaseManager

fetch_url_Nlines_wmin_wmax(hitemp_url='https://hitran.org/hitemp/')

requires connexion

fetch_urlnames()

requires connection

get_linereturn_format(opener, urlname, columns)

keep_only_relevant(inputfiles, wavenum_min=None, wavenum_max=None, verbose=True) → list

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)

Uncompress urlname into local_file. Also add metadata

Parameters:

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

• gfile (file handler. Filename: for info)

register()

register in ~/radis.json

get_last(b)

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

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

Returns:

• relevant (list of relevant files)

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