A demonstration IRAF/STSDAS script to perform aperture photometry on WFPC2 images of Omega-Cen has been developed and is described in this document. The primary goal is to provide an easy-to-use example that can help introduce observers to the use of scripts, and to demonstrate a few of the commonly used IRAF/STSDAS capabilities. It has been developed and tested under IRAF version v2.10.3BETA(08/18/94) for Sun OS 4.1. The script will also be used by the WFPC2 group at STScI as a template from which to test a wide variety of different effects on aperture photometry (e.g., hot pixels, CTE, undersampling, geometric distortions, edge effects, etc.). Two sections of auxiliary information are included. One section provides information on how to download the script and notes on running the script. The other section provides a list of other commonly used IRAF and STSDAS tasks for working with WFPC2 data, along with other useful information.
