Re: Mark IV is Taking Pictures

Mike and all,

You won't see these.  There are a couple of things I want to understand and
fix before I send any images out.  It is harder to repair the reputation of
bad data than to fix the problems.  Nothing serious (I hope).

A couple of clear nights and I will get things tuned up.  Then I will send
out another sequence on CD ROM.  Then everyone can get their software tuned
up.  I particularly hope for a version of Star that processes these larger
images.  I hope it is not a big job to do so.   We will also need catalogs
to work from for the whole sky.

It is clear that there are large scale patterns in the sky background with
features of size several degrees.  These seem to be as large as 10% of full
scale.  Will try to show you all some of these.  Of course, last night the
moon was nearing where I was looking, so they might not be so large on a
moonless night.

Even doing everything by hand, (i.e take image, store it, read it into
Image Scientist, look at it, write it out as .FTS) I was taking data at
about 10x the rate of a Mark III triplet.
