... We use the first XMM serendipitous source catalogue (1XMM) to compile a sample of normal X-ray galaxies . ... We combine our emission line sample with earlier works forming the most comprehensive X-ray selected galaxy sample for the study of the X-ray luminosity to the H? luminosity - a well-calibrated star-formation indicator - relation. ... We find that the X-ray luminosity strongly correlates with the H? luminosity, suggesting that the X-rays efficiently trace the star-formation. | ...

... Home . ... Data . Archives . ... Calibration . ... Following the installation of a new delivery of WFPC2 flat fields to the archive and pipeline databases, it has been discovered that a small number of these flat fields were incorrectly normalized. ... Note that when the science images above, or any science image, are retrieved from the HST archive using OTFR (On The Fly Reprocessing), the proper calibration files, including the correctly normalized flats listed above, will be applied to the data. ...

SAS home . ... EPIC background spectra are normally extracted from regions of the observation field-of-view, once "contamination" due to individual discrete celestial sources has been removed. ... In order to cope with this situation, blank sky event lists can be downloaded from the XMM-Newton Science Operations Center web site. ... It is in principle possible as well to extract background spectra from blank field event lists, if the spectrum accumulation regions are defined in sky coordinates. ...
