The XMM-Newton Serendipitous Source Catalogue, Version 1.0.1 XMM-Newton Survey Science Centre Consortium <XMM-SSC, Leicester, UK (2003)>
ADC_Keywords: X-ray sources ; Surveys ; Mission_Name: XMM Description: 1XMM is the first comprehensive catalogue of serendipitous X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory launched in December 1999, and has been constructed by the XMM-Newton Survey Science Centre (SSC) on behalf of ESA. Most (>80%) of the entries have not previously been reported as X-ray sources. The catalogue contains source detections drawn from 585 XMM-Newton EPIC observations made between 2000 March 1 and 2002 May 5; all datasets were publicly available by 2003 January 31 but not all public observations are included in this catalogue. Net exposure times in these observations range from less than 1000 up to about 100000 seconds. The total area of the catalogue fields is about 90deg2, but taking account of the substantial overlaps between observations, the net sky area covered independently is about 50deg2. The observations sample, albeit sparsely, most of the sky, with the exception of a 'hole' centered in the Cygnus region, caused by spacecraft observing constraints. The catalogue source detection and parametrization technique is optimized for point-like sources, and has been performed across several photon-energy bands (see "EPIC energy bands" below) and using data from each of the three EPIC cameras PN, MOS-1, MOS-2; the prefixes PN_ M1_ M2_ are generally used to designate the columns of the catalogue related to the detections by the corresponding camera. The catalogue in its FITS version has ∼ 400 columns; these include source-detection parameters (likelihood, position coordinates, counts, count rate, flux, hardness ratio, background estimates, errors etc), the results of cross-correlation with a large number of archival catalogues (SIMBAD, NED, USNO, GSC, APM, ROSAT etc), quality 'flags' resulting from visual screening, and 'meta-data' relating to the observation. For practical considerations the ascii version of the catalogue is made of 3 tables representing the sources, the observations and processing details, and the results of the cross-correlations; the names used as column names in the ASCII version are also reported within parentheses in the "Byte-by-Byte" descriptions below. Details about the construction of the catalogue can be found from the XMM-Newton Survey Science Centre ( EPIC energy bands: Narrow energy bands: 1 = 0.2 - 0.5 keV 2 = 0.5 - 2.0 keV 3 = 2.0 - 4.5 keV 4 = 4.5 - 7.5 keV 5 = 7.5 - 12.0 keV Broad energy bands: 6 = 0.2 - 2.0 keV = soft band, no images made 7 = 2.0 - 12.0 keV = hard band, no images made 8 = 0.2 - 12.0 keV = total band 9 = 0.5 - 4.5 keV = XID band File Summary:

Note (1): The total band flux (0.2-12keV) of the detections by the concerned camera (PN, M1, M2), and the mean flux (column Flux) weighted by the errors, all expressed in erg/cm2/s. A camera detection is only included in the calculation of the mean if the flags #1 (false detection), #5 (suspect position), and #6 (near-edge source) are all set to False (0) for this camera. This can lead to the situation where Flux is set to NULL for a valid source because none of the camera detections satisfy these criteria. It is to be treated as an upper limit if the source was not detected but observed with any one camera. Note (2): Value of the background map at the location of the detection by the concerned camera in counts per image pixel (the image pixel size is 4arcseconds). Note (3): Off-axis angle of the detection by the concerned camera (PN, M1, M2) in arcminutes, that is, the tangential radius from the nominal center of the focal plane (which is also the origin of the CAMCOORD2 system). Note (4): Total band source counts (0.2-12keV) of the detection by the concerned camera (PN, M1, M2) under the total PSF (point spread function) and corrected for background. Note (5): The detection position by the concerned camera (PN, M1, M2) is made of the CCD number, and the CCD-specific raw (x,y) pixel positions. Note (6): Distance to the nearest neighbour for the same exposure, on the concerned camera (PN, M1, M2) Note (7): Likelihood of the statistical fit to the cross-correlation of source matches of detections of this XMM observation with USNO-A2.0 coordinates. If the fit is reliable (posOK=1), the resultant correction is used to rectify the RA and Dec coordinates from the observation source lists (cols RAobs and DEobs) into corrected coordinates (cols RAdeg and DEdeg). Note (8): The likelihood values are computed from a simultaneous PSF fit to the source count distribution in each energy band. Note that likelihood values are related to the probability p of a detection occurring by chance by L=-ln(p). The expected number of spurious detections as a function of likelihood has been estimated by simulation to be about 10, 5, 2, 1 per EPIC exposure (i.e., for a single camera) at likelihood thresholds of 6, 8, 10, 12. Note (9): The hardness ratios are defined by: HR1 = (bd2-bd1)/(bd1+bd2) : [0.2-0.5keV] vs [0.5-2.0keV] HR2 = (bd3-bd2)/(bd2+bd3) : [0.5-2.0keV] vs [2.0-4.5keV] HR3 = (bd4-bd3)/(bd3+bd4) : [2.0-4.5keV] vs [4.5-7.5keV] The values are between -1 (softest) and +1 (hardest). Note (10): 12 verification flags are possible. The first 7 have been assigned the following meanings: 1 false detection 2 no visual inspection 3 the source lies within an extended region 4 there are nearby sources 5 the source position is suspect 6 the source is near an edge (of a CCD and/or the field-of-view) 7 a source comment is given The individual values of flags 1, 3, 5, 6 and 7 are reported in dedicated columns, with a value of 1 when the flag is set. The 12 flags are also reported as flag strings, with 'T' (true) indicating that a flag was set, and 'F' (false) a non-set flag; a dash (-) is used when the source was not observed or detected. A comment exists when the flag #7 is set. Note (11): The vignetting factor represents the fraction of the value of the exposure map at the position of the detection as compared to the value at the nominal point where the optical axis of the telescope in front of the camera intersects with the focal plane. For details see the 1XMM User Guide. Note (12): For each camera (PN, M1, M2) and each energy band, are given the encircled energy fraction (EEF) of the PSF within the cut radius of the subimage used for the PSF fitting. In this version the cut radiuses are identical in all energy bands.
