BSTAR2006 Grid: NLTE Departure Coefficients

These tar archive files contain one ASCII file for each model atmosphere. The individual files have the same structure than the model atmosphere files (Unit 7), but list the NLTE departure coefficients (b factors) in place of the NLTE populations. After the column mass of each layer, the file provides at each depth point the temperature, the electron density, the total mass density, and the NLTE b factors for all explicit levels.

The model atmospheres are available for 6 scaled-solar chemical compositions and 2 microturbulent velocities (only low gravity models, log g <= 3.0, at Vt = 10 km/s):
