Stellar parameters from a file? (please use the same format)

Star_name(unique per line) Teff log(g) [Fe/H] Vmic ( Vmac Vrot : optional)

Star1 5777 4.44 0.00 1.0

Input from a file ? select file:

Spectral interval : from to few selected spectral lines
compute only molecular lines (below 12700 angstroms)
R:[λ/dλ] (put 0 for no convolution -fastest)

Add gaussian noise? SNR Change spectral sampling (default 5 mÅ): mÅ

Overplot an observed stellar spectrum? select file (only text table supported):
Radial velocity (km/s)
