[guide-user] Problem with USNO-A2.0

Jari Suomela Dec 23, 1999

Hi Bill,

I just noticed a small problem with data from USNO-A2.0 at 17h 51min,
-35 deg 09'. There's a rectangular area about 25' by 12' nearly devoid
of stars and just east of this is an area packed with A2.0 stars with
oddball magnitudes, the difference between R and B being around 10
mags. This is most probably a USNO-A2.0 related problem, but perhaps
you should check that Guide isn't the cause of this before I report it
to Dave Monet.
