# 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.
