FITS files

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.
