Production Plan

[droege@snapmail.us]

I am starting to write production code.  Here is the plan:

1) At dusk take a dark set.  These really do not change much but now that
I have Rob's code I can do a better job of running everything and might as
well take darks as they do not cost observing time.

2) Look at where I can point the telescope.  Then look at a table of tiles
to see which it the best tile to take.

3) Point the telescope at the tile and take a set of images to make a
flat.  This is done by offsetting the telescope slightly in all directions
to get sky flat data.

4) Point at the tile and follow it as long as possible taking images.  For
tom1 this is two hours.  For tom2,3,4,5 it may be 3 or a little more
hours. This might produce a 30 image sequence at 200 second exposure for
tom1 and 45 images for the rest.

5) Repeat 4 until dawn.  Possibly take another set of darks at dawn.

With experience, we might do the flat sequence less often.  I need an easy
way to compare flats and darks to determine how often to take them.  At
present I have to move files to a Windoz machine where I have Mike
Gutzwiller's Image Scientist.  (Mike do you have a linux version of IS?) I
have been using DS9 as my main image viewer but it does not have commands
to divide one image by another or subtract one image from another.  Does
anyone know of a convenient .fits tool that does this? (iraf is not a
"convenient" fits tool for me yet)
