The ferre_to_specint tool extracts a series of flux spectra from a data file in FERRE format, and writes them to specint files. It accepts the following command-line arguments:
ferre_to_specint
<ferre_file_name>
Name of input FERRE file.
<ferre_file_type>
Type of input file. This determines the mapping between photospheric parameters given in the input file, and photospheric parameters written to the output file. Supported options are CAP18 (for the :ads_citealp:allende:2018 grids).
<specint_prefix>
Prefix of output specint files; these will have the name <specint_prefix>-NNNNNNNN.h5, where NNNNNNNN is the zero-padded index of the spectrum (starting at 1).
