Given a location in the HR diagram, this program allows you to determine the stellar parameters associated with this point. To proceed, select the metallicity
and then enter the color and magnitude
of the observational data. You are also able to simulate observational uncertainties. The results will be displayed on the screen and can be saved by typing Alt + S.
They include the stellar mass, age, radius, luminosity, effective temperature.
By default the program will give you the mass, radius and age
of the star assuming it is on its pre-main sequence track.
If you use colors and magnitudes, the data are converted in the different bands using either the conversion table from Kenyon and Hartmann (1995, AJSS 101,
117) or the one compiled by Siess et al.
(1997, A&A 324
, 556). Note that in the latter case, only the B,V,R and I magnitudes are available. The colors are expressed in the Cousins
