The count rates conversion is made with the assumption that the full PSF is sampled. In case of partial PSF sampling the magnitudes have to be corrected by the calling task.
The transformation of the input count rate
into the natural system
(in units of magnitude)
is described by the equation:

The original routine has been aliased as CAL_omNaturalMagnitude.
