Introduction

xmmselect is a GUI (Graphical User Interface) meta-task which allows the SAS user to control the generation of final products, i.e., filtered event lists, images, histograms, OGIP spectra/rate curves, Auxiliary Response Files (ARFs), and Redistributuion Matrix Files (RMFs) from an initial event list data set in an interactive manner. It is intended to be used quite extensively in a typical analysis session in which the user will want to start from a calibrated event list as created by the automatic pipeline processing and generate OGIP-compliant products eligible for the final stages of interactive analysis, such as, spectral fitting with Xspec, and timing analysis with Xronos.

In this process one wants to enter a loop of stepwise refinements of the products in question:

1. Filter the event list under the control of a boolean selection expression
2. Accumulate a product from the events which passed the filters
3. Visualize the product
4. Correlate features in the products with made selections and refine the selection
5. Go back to step 1.

xmmselect provides functionality to perform this type of processing in a convenient manner.
