rubin_sim.phot_utils.calc_gamma(bandpass, m5, phot_params)

Calculate the gamma parameter used for determining photometric signal to noise in equation 5 of the LSST overview paper (arXiv:0805.2366)

@param [in] bandpass is an instantiation of the Bandpass class representing the bandpass for which you desire to calculate the gamma parameter

@param [in] m5 is the magnitude at which a 5-sigma detection occurs in this Bandpass

@param [in] phot_params is an instantiation of the PhotometricParameters class that carries details about the photometric response of the telescope.

@param [out] gamma
