The aim of eslewchain is to produce scientifically useful products from an XMM-Newton slew. It is designed to work with data from the EPIC-pn or EPIC MOS cameras.
eslewchain takes as input a slew event file and associated attitude files and produces a series of images and exposure maps. The task divides the event set into chunks of 72000 sky pixels (roughly 1 degree) in either the X or Y dimension, depending on the direction of the slew. These mini event files are then attitude corrected to project them onto the local tangential plane and then used to create the products. Data products are produced in a number of photon energy bands
1 = 0.2-0.5 keV
2 = 0.5-1.0 keV
3 = 1.0-2.0 keV
4 = 2.0-12.0 keV
5 = 0.2-2.0 keV
0 = 0.2-12.0 keV
