result = ajs_double_schechter(absmag [, params] [, mstar=mstar] [, alpha_1=alpha_1] [, phistar_1=phistar_1] [, alpha_2=alpha_2] [, phistar_2=phistar_2] [, loglum=loglum])
This function generates a double Schechter function (single value of M-star, but two values for alpha and phi-star) along an input array of absolute magnitudes.
Compatible with mpfit
Return value
Array of phi for corresponding absmag
Parameters
- absmag in required
Array of absolute magnitudes
- params in optional
[mstar, alpha_1, phistar_1, alpha_2, phistar_2] OR input separately:
Keywords
- mstar in optional
- alpha_1 in optional
- phistar_1 in optional
- alpha_2 in optional
- phistar_2 in optional
- loglum in optional
