Abstract

For about five years SRG/eROSITA is the first X-ray telescope in orbit around the second Lagrangian point L2. We present an updated study of its instrumental background based on cleaned data and improved simulations, carried out in the framework of the eROSITA Background Working Group. We also report some analysis of soft proton contamination, from which we make an estimate of the encountered orbital flux. Finally, we outline some ongoing work about pattern analysis in the case of minimum ionising particle rejection switched off.
