With V1.0, I have included a quick redux program. Of course, it only has a chance to work with the setups that V1.0 supports. Anyhow, give this a shot and hope for the best: (Odds are you have to be on your laptop for all of this and you will have to have installed all of the code.) 1. Create a temporary directory 2. Put a Science frame in the directory and an Arc and Flat corresponding to the Science setup 3. Launch IDL 4. IDL> hires_qckrdx, Arcfil, Flatfil, Objfil If you do this more than on more than one setup, you should set SETUP=# for each additional setup where # > 1 and increases. ------------- -- It is unlikely that Keck folks have setup my code yet. I will work on this shortly. -- A nice bonus of trying this at the telescope is that you will know right away if you have the correct calibrations taken.
