eslewsearch (eslewchain-1.17.1) [xmmsas_20190531_1155-18.0.0]

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.
