List of f/48 PSF images.

These images are the best currently available for use as PSFs
on f/48 imaging data. They relate to the current secondary mirror
position.
Count-rates are given as `equivalent 512x512' rates. For PSFs
where the imaging mode was not 512x512(NORMAL), the actual count-rates
are given in parenthesis.

HISTORY
~~~~~~~ 10-SEP-1991 File Created Dave Baxter.
20-OCT-1991 Added PSF f220w_a (from Platescale data
Proposal 2807) Dave Baxter.
02-DEC-1991 Added data from proposal 3812 (f48 PSFs).
The following PSFs have been added;
f175w_a f342w_a
f220w_b f430w_a
f275w_a
These PSFs are, in general, poor. Dave Baxter.
