evselect (evselect-3.71.2) [xmmsas_20230412_1735-21.0.0]

Description

Among the suite of individual SAS tasks evselect is of central significance. It serves two complementary purposes

1. Filter event list data controlled by user-specified selection criteria
2. Extract images, spectra, and time series from the filtered event list obtained in the first step. The filtered list is selectable for output as well.

The availability of both features within a single task allows the user to generate useful products from an event list (e.g., create a rates file in the energy band 0.5 – 3 key from the X-ray source lying within a circle of 10 arcsec radius in the center of the FOV) in a convenient manner.
