eslewsearch (eslewchain-1.20.1) [xmmsas_20230412_1735-21.0.0]

General

The aim of eslewsearch is to produce lists of sources detected in an XMM-Newton slew. It is designed to work with data from the EPIC-pn camera.

eslewsearch takes as input a set of slew images and exposure maps which have been previously created by the task eslewchain. It runs the following sequence of SAS tasks separately on the soft band (0.2–2 keV), hard band (2–12 keV) and total band (0.2–12 keV) subimages.

1. emask expimageset=EXPMAP
2. eboxdetect usemap=no (local mode)
3. esplinemap (make the background map)
4. eboxdetect usemap=yes (map mode)
5. emldetect

The individual source lists are combined using the ftools, ftlist, fcreate, fsort into a single file.
