Make Lyot stop geometry param[in] IDincoh_name Incoherent Lyot pupil intensity response to off-axis sources parampin] IDmc_name Intensity Lyot pupil image for on-axis source

explores two thresholding methods applied together : (1) keeps pixels for which offaxisLight / onaxisLight > rsl (2) keeps pixels for which onaxisLight < v0 selects the mask that achieves the strongest on-axis rejection while satifying the throughput constraint
