Alpha [alpha/Fe]: The alpha enrichment parameter to be used for the calculation of the Synthetic CMD. Values from 0.0 to 0.6 can be used.
Metallicity: Metallicity for the Synthetic CMD between the range of 0.0 and 0.08.
Age: The age of the stars given in Gyrs for the calculated Synthetic CMD.
Initial Number of Stars: The number of stars to be used in the calculation of the Synthetic CMD. A maximum of 100000 stars is currently allowed.
IMF slope: Value for the slope of the IMF you would like to use. (i.e. 1.35 for Salpeter)
IMF upper limit: The upper mass limit of the IMF in solar masses.
IMF lower limit: The lower mass limit of the IMF in solar masses.
ISEED: The random number generator seed to be used for the Synthetic CMD calculations. This allows the use to get back previously made Synthetic CMDs.
Binary Fraction: The fraction of binary stars for the calculated Synthetic CMD given as a number between 0.0 and 1.0.
qmass: Mass fraction for binary stars given as a number between 0.0 and 1.0.
