APO User,

The observatory has gotten a few requests from 3.5-m users for a
convenient method of matching their science exposures to guide (or
slit viewer) camera exposures for later analysis of their data.
Unfortunately, it would prove quite difficult or impossible to get
this information correct, in the image headers, and in a timely
fashion while an observer is  collecting, downloading, and
inspecting their raw data.

As an alternative we are making a number of post processing scripts
available on newton.apo.nmsu.edu, accessible from each of the
institutional accounts to provide this information to you. These
scripts can be run anytime after your observing run (up to the year
that raw data resides at APO) to generate a text log matching up
your science frames to associated guide/ slit viewer frames.

The scripts for matching the echelle  to the echelle slitviewer
frames , dis  to dis slitviewer,  triplespec to triplespec
slitviewer and na2guider to any of the na2 mountable instruments
(dis, spicam, nicfps, triplespec, gfp) respectfully are:

  ecam_match
  dcam_match
  tcam_match
  gcam_match

For more information on how to run these programs and what
information they provide go to:

http://www.apo.nmsu.edu/arc35m/Guider_match_scripts.html

or follow the drop down menu from the "Telescope & Instrument
Information" page that is called "Observing Tools" and select
"Guider match scripts".
