Disk Set 18

[Tom Droege <tdroege@veriomail.com>]

I will shortly be putting together disk set 18.  I am open to suggestions 
as to what to put on the disks.  I will have about 9-10 days of data.  The 
recorded format is 7 object images and a dark, repeated through the 
night.  The object images overlap, so a star will appear on 5 or 6 
images.  I thought I might make darks and flats for each evening of 
data.  I can do this with "Image Scientist" but the result does not contain 
the complete fits header.  However by making flats here, I could use more 
images for a median flat that I could afford to put on the disks.

So I might use 20 or so images from each night's run to make a median 
flat.  Then I would include a few images over the same piece of sky from 
each night of good data.  With 10 or so images from each night there would 
be a lot of overlap.  One might get 40-50 measurements for each star.

Suggestions please.

As usual, send me your name and address (if you have not already done so) 
to get a set when I finish making it.
