Wilkinson Microwave Anisotropy Probe
This is a catalog of 390 point sources detected in the five year WMAP sky maps independently from any previous surveys. The sources listed in the catalog were detected as ≥ 5 sigma peaks in WMAP maps that have been weighted by the square root of the number of observations and optimally filtered for point source detection. The position of each source is obtained by fitting a Gaussian profile plus a baseline to each detected peak. Of the 390 detected sources, 373 have one or more possible 5 GHz counterparts. Of the sources with no 5 GHz identification, some are close to the detection threshold and may be spurious. The catalog lists the following parameters for each source:
| Cols 1 -- 2 | Right Ascension and Declination (2000) |
| Cols 3 -- 4 | Galactic Longitude and Latitude |
| Cols 5 -- 9 | WMAP Flux (Jy) |
| Cols 10 -- 14 | Flux Error (Jy) |
| Cols 15 -- 16 | 5 Ghz Identification |
| Col 17 | Flag for multiple 5 GHz identifications |
| Col 18 | WMAP DR1 Identification Number |
| Col 19 | WMAP Spectral Index |
| Col 20 | WMAP Spectral Index Error |
A special point source catalog mask was used to exclude Galactic Plan and Magellanic cloud regions in the production of this catalog. See the masks description for more details regarding this mask.
