The user needs to specify the following parameters:
a) mean HB mass;
b) 1sigma dispersion of the Gaussian Distribution;
d) heavy element mixture: scaled solar or alpha-enhanced;
e) the photometric system;
The output provides magnitudes and properties of the objects within the RR Lyrae instability strip. For stars located in the "OR" region - where both fundamental and first overtone pulsational mode can be stable - the code provides the fundamental mode pulsation period.
The output summarizes also the total number of blue HB stars - those located on the blue side of the RR Lyrae instability strip -, red HB stars - those located at an effective temperature lower than the Red Edge of the RR Lyrae instability strip, and Asymptotic Giant Branch stars.
