Summary release note for ppsprod-19.16 ======================================= Pipeline Version: 19.16_20210326_1200 Pipeline name: ppsprod Release Date: 2021-03-26 SAS Manifest: xmmsas_20210310_1620 Summary ======= This version of the pipeline is based on public SAS19 version and does not include major changes related to source detection although the method to filter flaring background periods in observations with multiple exposures in a given EPIC has been modified (see below). Improvements in calibrations are not listed here as they can be found in SAS and/or CCFs release notes. Only the main changes that result in new products or modifications to the content of existing ones are listed here: i) a new product is included for sources that might suffer pile-up effects in EPIC-pn camera. A file with multiple spectra (OGIP compliant) is created with i.1 only single events in the nominal circular source extraction region i.2 only double events in the nominal circular source extraction region i.3 single and double events in a series of annular extraction regions with increasing core excising radius. ii) the same threshold level is applied to all exposures of the same EPIC camera within the same observation. In-band background light curves from the individual exposures are combined to find the threshold level that optimizes the detection of the weakest sources iii) lightcurves of OM sources detected in Fast Mode windows in multiple exposures are combined into a single plot and FITS file. iv) OM rates are saved in an OGIP compliant PHA spectrum file for sources identified as possible counterpart of an EPIC source. v) for EPIC sources having OM sources within their position error circle a plot is created with the EPIC fluxes in the 5 standard energy bands and the fluxes of the OM sources through the available OM filters. The file with the plot also includes images of the OM in all available filters within the EPIC source error circle and the corresponding EPIC 3-colour image. The version of SAS being used is a pipeline-specific manifest xmmsas_20210310_1620. This is based on the public SAS release 19.0.0, described at http://www.cosmos.esa.int/web/xmm-newton/sas-release-notes-1900 Documentation ============= Documentation for this pipeline can be found at: http://www.cosmos.esa.int/web/xmm-newton/pipeline and links therein.
