News #255, 28 July 2022 CONTENTS [1]XMM-Newton Users Handbook update for AO-22 [2]New versions of the XMM-Newton Serendipitous Source Catalogues: 4XMM-DR12 and 4XMM-DR12s [3]XSA V15.0 RELEASE WITH ACCESS TO the 4XMM-DR12 and 4XMM-DR12S CATALOGUES [4]Documentation updated: EPIC Calibration Status and XMM-Newton Background documents NEWS XMM-Newton Users Handbook update for AO-22 The XMM-Newton Users Handbook (UHB) has been updated to version 2.20 in preparation for the next Announcement of Opportunity (AO-22) which will open next 17th of August. The UHB contains information on the instrumentation on board XMM-Newton and serves as the main technical support document for proposal preparation, based on which potential XMM-Newton users can assess the technical feasibility of their planned observations. The XMM-Newton Users Handbook is on-line at [5]https://xmm-tools.cosmos.esa.int/external/xmm_user_support/documenta tion/uhb/ Alternatively, pdf and postscript versions of the UHB can be downloaded from the "XMM-Newton Proposer's Info and Manuals" portal [6]https://www.cosmos.esa.int/web/xmm-newton/documentation New versions of the XMM-Newton Serendipitous Source Catalogues: 4XMM-DR12 and 4XMM-DR12s A new version of the XMM-Newton EPIC Serendipitous Source Catalogue, 4XMM-DR12, has been released by the XMM-Newton Survey Science Centre (XMM-SSC) in collaboration with the SOC. This version includes an extra year of data with respect to 4XMM-DR11. 4XMM-DR12 includes 939270 X-ray detections which relate to 630347 unique X-ray sources from 12712 observations that were public by the 31st December 2021. 4XMM-DR12 covers a total sky area, with at least 1 ks exposure, of 1283 square degrees if overlaps are taken into account, where some regions of the sky have been pointed as many as 84 times. Around 9% of all the detections are classified as extended, and spectra and time series have been extracted for 36% of the detections. The median positional uncertainty of the catalogue detections is 1.57 arcseconds (with a standard deviation of 1.43). Median fluxes in the catalogue are ~5.2E-15 and ~1.2E-14 erg/cm2/s in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively. With the detection catalogue 4XMM-DR12, we release the stacked catalogue 4XMM-DR12s, created from overlapping observations. Stacking results in better source parameters, higher sensitivity, and direct access to measures of long-term flux variability. 4XMM-DR12s is built from 1620 groups drawn from 9355 observations. Each group includes between 2 and 372 observations. Stacked source detection is performed on all overlapping exposures of reasonable quality. For the first time, parameters from PSF photometry on lower-quality exposures are provided as well. 4XMM-DR12s contains 386043 sources, of which 298626 have several contributing observations. It reaches a median depth of ~2.5E-15 and ~6.8E-15 erg/cm2/s in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively. 6868 sources are variable on the long term. The detection catalogue is described in the paper [7]Webb et al. (2020) and the stacked catalogue is further described in [8]Traulsen et al. (2020). Details of the catalogue, the catalogue files and full 4XMM documentation are available on the [9]XMM-SSC webpages at: [10]http://xmmssc.irap.omp.eu/Catalogue/4XMM-DR12/4XMM_DR12.html and [11]https://xmmssc.aip.de/cms/catalogues/catalogue-4xmm-dr12s FITS files containing summary information about the observations used in the catalogue are also provided. FITS and CSV versions of the full 4XMM catalogue and a slimline version of the FITS file are also available for download at: [12]http://www.cosmos.esa.int/web/xmm-newton/xsa The slimline version of 4XMM-DR12 has only one row per unique source (rather than per detection as in the main catalogue) and a reduced number of columns that essentially pertain to the unique source quantities. Alongside the XSA user interface, 4XMM is also distributed through: XCATDB [13]http://xcatdb.unistra.fr/4xmmdr12 HEASARC [14]http://heasarc.gsfc.nasa.gov/W3Browse/xmm-newton/xmmssc.html, and [15]https://heasarc.gsfc.nasa.gov/W3Browse/xmm-newton/xmmstack.html IRAP [16]http://xmm-catalog.irap.omp.eu/ XSA V15.0 RELEASE WITH ACCESS TO THE 4XMM-DR12 AND 4XMM-DR12S CATALOGUES A new version of the XMM-Newton Science Archive (XSA v15.0) is available at [17]https://www.cosmos.esa.int/web/xmm-newton/xsa XSA v15.0 provides access to the new versions of the 4XMM-DR12 and 4XMM-DR12s Catalogues. Documentation updated: EPIC Calibration Status and XMM-Newton Background documents New versions of the following documents have been released: * EPIC Calibration Status available from the [18]XMM-Newton Calibration Portal. * The Behaviour of the XMM-Newton Background available from the [19]XMM-Newton Background Analysis page.
