TL;DR: In this article, a data processing algorithm for angular reconstruction and event selection applied to 2D photoelectron track images from X-ray polarimeters is presented, which reconstructs the initial emission angle of a photo-electron from the initial portion of the track, which is obtained by continuously cutting a track until the image moments or number of pixels fall below tunable thresholds.

Suzaku Constraints on Soft and Hard Excess Emissions from Abell 2199
Madoka Kawaharada,Kazuo Makishima,Takao Kitaguchi,Sho Okuyama,Kazuhiro Nakazawa,Yasushi Fukazawa +5 more
TL;DR: In this paper, the X-ray luminosity of the Abell 2199 galaxy cluster was measured in X-rays, with five pointings for 20 ks each, and the upper bound was shown to be 3.7-7.6 times tighter than the detection reported with XMM-Newton.
