List of CAL Routines used

The whole procedure outlined before is done by using several routines:

CAL_omGetPSF

controls the pointers for the next routines

CAL_omPsfEncircledEnergy

computes the fraction of the energy contained in a circle of a given radius centered on the PSF centroid

CAL_omPsfCircleRadius

computes the radius of a circle centered on the PSF barycentre containing a given fraction of the total energy
