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
and a
complete description of any task with
