petitRADTRANS line-by-line opacities

A copy of the line-by-line opacities that petitRADTRANS publishes on its public Keeper share (https://keeper.mpdl.mpg.de/d/e627411309ba4597a343/), with the share's folders and file names unchanged.


Layout	one folder per species, as named on the share
Cross-sections	`sigma_<id>_<T>.K_<P>bar.dat`: the species' cross-section (cm² per molecule) at temperature T (K) and pressure P (bar), on the wavelength grid of `wlen.dat` (cm)
Grid	`PTpaths.ls`, where present: each file's pressure (bar), temperature (K) and name
Species	`molparam_id.txt`: the species' identifier and its molparam value, the isotopologue's natural abundance
Format	little-endian 64-bit floats, as petitRADTRANS reads them; some files carry a 4-byte Fortran record marker at each end

Citation

The opacities are the petitRADTRANS team's (Mollière et al. 2019, A&A 627, A67). Each species rests on its own line list, whose references petitRADTRANS's documentation gives (https://petitradtrans.readthedocs.io/en/latest/content/available_opacities.html); cite them with any use of these files.
