PSF Factors for OLP10
=====================
07/12/2000	Bernhard Schulz

This vector contains the PSF correction factors for 
a point source centred over
the standard apertures of PHT-P and 
the arrays of PHT-C (assuming a summation of the 
individual fluxes of all pixels)

The factors for PHT-P and the factors for the pixel centred
PHT-C observations are calculated taking into account the 
filter profiles and a nuFnu = const. reference source spectrum
and assuming standard design geometry (Schulz 2000).
The integrated array factors were derived using the ratios
between pixel and array centred observations as derived 
by Laureijs (1999). The factors appear in tables 5 and 6 
(column "measured") of Schulz (2000).
