The atmospheres are store in FITS binary tables with the columns:
- Optical depth “tau”.
- Temperature “temp” in units of K.
- Gas pressure “pgas” in units of dyn/cm^2.
- Density “rho” in units of g/cm^3.
- Electron partial pressure “pe” in units of dyn/cm^2.
The header keywords are essentially the same as for the high resolution spectra, as can be found here.
