List of PROS and Selected IRAF Tasks

This section lists all PROS tasks (some of which are not described in this guide) and some useful IRAF tasks which are included. It is our intent to add instructions for tasks that are particularly useful in x-ray analysis. A brief description of all tasks in a given package can be obtained by typing \fbox{help package-name} and a complete description of any task with \fbox{help task-name}.
