Hi Aimee,

Data calibration is explained in the Athena User's Guide:

http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/process/cal.html

If that is too terse or does not address your question, you might
consider making a small Athena project file which demonstrates what
you are confused about and then post that to the mailing list.
Posting data is usually the best way to get a concrete answer.
