Overview

The authors have obtained a deep 8-field XMM-Newton mosaic of M33 covering the galaxy out to the D25 isophote and beyond to a limiting 0.2-4.5 keV unabsorbed flux of 5 x 10-16 erg cm-2 s-1 (L > 4 x 1034 erg s-1 at the 817 kpc distance of M33). These data allow complete coverage of the galaxy with high sensitivity to soft sources such as diffuse hot gas and supernova remnants (SNRs). In the reference paper, the authors describe the methods they used to identify and characterize 1296 point sources in the 8 fields. They compare their resulting source catalog to the literature, note variable sources, construct hardness ratios, classify soft sources, analyze the source density profile, and measure the X-ray luminosity function (XLF). As a result of the large effective area of XMM-Newton below 1 keV, the survey contains many new soft X-ray sources. The radial source density profile and XLF for the sources suggest that only ~15% of the 391 bright sources with L > 3.6 x 1035 erg s-1 are likely to be associated with M33, and more than a third of these are known SNRs. The log(N)-log(S) distribution, when corrected for background contamination, is a relatively flat power law with a differential index of 1.5, which suggests that many of the other M33 sources may be high-mass X-ray binaries. Finally, the authors note the discovery of an interesting new transient X-ray source, which they are unable to classify.

The list of XMM-Newton observations used for this survey is given in Table 1 of the reference paper. The data reduction and source detection techniques are described in Section 3 of this same reference.

The unabsorbed energy conversion factors (ECF) values for different energy bands and instruments that were used in this paper are as follows (the units are 1011 counts cm2 erg-1):

Provenance

This table was created by the HEASARC in July 2015 based on an electronic version of Table 3 of the reference paper, the list of XMM-Newton X-ray point sources detected in a deep 8-field mosaic of M33, which was obtained from the ApJS web site.

Parameters

Source_Number
A unique X-ray source number in order of increasing J2000.0 Right Ascension.

Name
The name of the XMM-Newton X-ray source, using the '[WWH2015]' prefix (for 'Williams, Wold, Haberl 2015', and the source number, e.g., '[WWH2015] 1'. Notice that, in the original tables, the authors did not define a naming convention, so that the HEASARC has created these names following the precepts of the CDS Dictionary of Nomenclature of Celestial Objects. An alternate name can also be created using the 'XMMU' prefix (for XMM-Newton, unregistered) and the J2000.0 equatorial coordinates truncated to 0.1 seconds of time in RA and 1 arcsecond in Declination, e.g., 'XMMU J013131.1+303119' for source number 1.

RA
The Right Ascension of the XMM-Newton X-ray source in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.01 seconds of time in the original table.

Dec
The Declination of the XMM-Newton X-ray source in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.01 arcseconds in the original table.

LII
The Galactic Longitude of the XMM-Newton X-ray source.

BII
The Galactic Latitude of the XMM-Newton X-ray source.

Error_Radius
The X-ray source positional uncertainty, in arcseconds.

FB_Detect_Likelihood
The total-band (0.2-4.5 keV) detection likelihood, DL, of the XMM-Newton X-ray source, where DL = -ln(p), and p is the probability that no source is present, including all of the observations (all bands, all cameras) measured.

FB_Counts
The net counts in the XMM-Newton X-ray source combined across all cameras and bands (0.2-4.5 keV) measured by simultaneously fitting the EPIC PSF to all observations of the source in all bands and cameras.

FB_Counts_Error
The uncertainty in the net X-ray source counts combined across all cameras and bands (0.2-4.5 keV) measured by simultaneously fitting the EPIC PSF to all observations of the source in all bands and cameras.

FB_Count_Rate

FB_Count_Rate_Error

FB_Flux

FB_Flux_Error
The uncertainty in the unabsorbed energy flux of the XMM-Newton X-ray source combined for all bands (0.2-4.5 keV), combining all measurements in the separate bands and cameras with their respective energy conversion factors (ECFs), in erg cm-2 s-1.

Source_Flags
This parameter contains flags indicating any deficiencies with the detection or characterization of the XMM-Newton X-ray source, as follows:

  Value   Meaning (Number of affected sources)

  0       No problems (904 sources);

  ip      A few hot pixels in an image (27 sources);

  is      An associated streak from a nearby bright source (29 sources),

  m       High detection likelihood, DL, in one MOS camera but not the other MOS
          camera or the PN (138 sources);

  pn      Much higher DL in the (0.2-4.5 keV) PN data than in any other band
          camera (35 sources): such sources are likely to be spurious unless
          they have a match in another survey;

  s       A source that was not measured in all 3 cameras (167 sources). In these
          cases, the total measurements are repeats of the measurements from the
          camera that detected the source (for single camera detections) or
          weighted mean measurements from the two cameras that detected the
          source. These sources are not likely spurious,but their combined
          measurements were not performed by emldetect;

  t       Sources with 0.2-4.5 keV source counts that are more than a factor of
          2 different from the sum of the source counts measured in the
          individual band cameras (suggesting a problem with the merged
          measurement), or with total counts in an individual band more than a
          factor of 2 different from the sum of the source counts measured in
          the individual cameras for that band, likely due to a limitation of
          the combining algorithm. Thus, for the 44 t-flag cases, the sources
          themselves are not spurious, but the total combined measurements are
          not as reliable. Thus, the authors do not use the combined totals for
          analysis. They only analyze the individual band (or band camera)
          measurements, as emldetect produced inconsistent results in the stack
          of all band camera data at these locations.

Hardness_Ratio_1
The hardness ratio HR1 of the XMM-Newton X-ray source, where HR1 = (M - S)/(S + M + H), where H, M, and S represent the fluxes of the sources in the three bands (defined below). The authors computed the HRs using the source fluxes from their four energy bands for all unflagged sources, sources with the 's' or 't' source flag values, and flagged sources matched to Tullmann et al. (2011, ApJS, 193, 32). All fluxes are unabsorbed and assume a power-law spectrum with an index of 1.7 and an absorption of 6 x 1020 cm-2. For sources with the 's' or 't' flag, the authors adopted the PN fluxes for each band. If the measured rate or flux is 0.0 in any of the bands, then they adopt the upper limit from emldetect (see Section 3.5 of the reference paper) as the rate or flux for that band when computing the HRs. The 0.2-0.5 keV ('sb0') and 0.5-1.0 keV ('sb1') bands were combined into one soft (S) band, while 1.0-2.0 keV ('mb') and 2.0-4.5 keV ('hb') made up the medium (M) and hard (H) bands, respectively. These bands make the HRs listed herein easier to compare with other surveys.

Hardness_Ratio_2
The hardness ratio HR2 of the XMM-Newton X-ray source, where HR2 = (H - M)/(S + M + H), where H, M, and S represent the fluxes of the sources in the three bands (defined below). The authors computed the HRs using the source fluxes from their four energy bands for all unflagged sources, sources with the 's' or 't' source flag values, and flagged sources matched to Tullmann et al.

The 0.2-0.5 keV ('sb0') and 0.5-1.0 keV ('sb1') bands were combined into one soft (S) band, while 1.0-2.0 keV ('mb') and 2.0-4.5 keV ('hb') made up the medium (M) and hard (H) bands, respectively. These bands make the HRs listed herein easier to compare with other surveys.

The ratios HR1c and HR2c were developed specifically for use with XMM-Newton data to take advantage of its soft-band sensitivity. The authors only include sources with enough counts in these bands to have uncertainties on HR1c and HR2c of <= 0.2.

Hardness_Ratio_2c
The soft-band hardness ratio HR2c of the XMM-Newton X-ray source, where HR2c = (M - S1)/(S1 + M), where S1 and M represent the fluxes of the sources in the 0.5-1.0 keV ('sb1') and 1.0-2.0 keV ('mb') bands. The ratios HR1c and HR2c were developed specifically for use with XMM-Newton data to take advantage of its soft-band sensitivity. The authors only include sources with enough counts in these bands to have uncertainties on HR1c and HR2c of <= 0.2.
