Here are some notes on running the script taken from the wfpc2_script1 file:
# Notes: 1. If you are not familiar with IRAF/STSDAS, please consult
the STSDAS Users' Guide and your site-specific IRAF manual.
( http://ra.stsci.edu/About3.html#Introduction )
# 2. The following tasks need to be loaded in IRAF (Note that you
# can put these in your login.cl if you wish rather than
# typing them each time):
# stsdas.hst_calib.wfpc
# toolbox.imgtools
# imred.ccdred
# images.tv
# noao.digiphot.apphot
# ttools
# proto
# 3. You can run the full script using: cl < wfpc2_script1
# or use your mouse to cut and paste part of the script
# to run only portions of the full script. Portions
# can be commented out using # in the first column.
# 4. An attempt has been made to include explicitly some of the
# parameters that are commonly changed, but you should
# examine the rest of the parameters (e.g., help gcombine, or
# epar gcombine) to make sure they are appropriate.
# 5. The script is currently set up to work on only the PC
# (i.e., group number 1, denoted by [1]). You probably want
# to change the apertures and zeropoints for the WF chips.
# 5. These particular observations used the gain=14 channel.
# The zeropoints will be about +0.75 mag for the more
# commonly used gain=7 channel. See the Holtzmann article
# or the Whitmore Calibration Workshop paper for details.
