Data model: calibPhotom

General description: This file contains the PT calibration results for a RUN/CAMCOL. Final calibration is given as the nanomaggies per count, the factor by which to multiply the raw counts of each object:

nmgypercount = a × 10^{0.4 × kterm × airmass}

Naming convention: calibPhotom-RUN6-CAMCOL.fits

Approximate size: 200 kbytes.

• npatch[5] (int32): number of patches for each band
• nstar[5] (int32): number of star matches for each band
• cloudcam[5] (int16): cloud camera status in each band
• tai[5] (float64): TAI-format time each band was observed in (ugriz)
