Conversion from counts per second to physical quantities
Conversion of spectral data expressed as cps into irradiance, transmittance or reflectance.

A source_spct, filter_spct or reflector_spct object containing the spectral values expressed in physical units.
In contrast to other classes defined in package 'photobiology', class "cps_spct" can have more than one column of cps counts in cases where the intention is to merge these values as part of the processing at the time the calibration is applied. However, being these functions the final step in the conversion to physical units, they accept as input only objects with a single "cps" column, as merging is expected to have been already done.
