Usage in processing:	 section 8.4.9, 8.4.10
File Type:		 FITS Image 
Units:		 	 dimensionless
File Name:		 PPSF 
This calibration product lists for each wavelength band of PHT-P the fraction of the point source power that passes a given aperture size. The correction factors are needed in the conversion from power on the detector in W to point source flux in Jy.

For the C100 and C200 arrays the fraction of point source power falling on the entire array is listed.
