II. User's Guide to the 2MASS All-Sky Data Release
3. XSC Parameters
a. Column Descriptions
The XSC contains 389 columns of information per source (most of which is photometry.) Because extended sources are much more complicated than a point source, it takes many more parameters to characterize them. Some parameters are required to describe the spatial extent of a source, and many more are required to characterize the photometry. In addition to a number of standard measures of photometry, the xsc also reports the magnitude as measured in a number of different fixed-size apertures. The columns are described in the tables below. We have separated the columns according to their basic function and utility.
Photometry algorithms and performance, "Large Aperture Photometry: Profile Fitting, Isophotal & Total Mags," is discussed in Section IV.5e. The XSC FAQ and Primer, "How to Use the 2MASS XSC -- FAQ Sheet," is Section II.3b.

A. Name and Position Information
| column | Parameter Name | View | Format | Units | Description |
|---|---|---|---|---|---|
| 1 | jdate | L | 13.4f | day |
Julian date of the source measurement accurate to ±3 minutes.
This value is the mean Julian date of the scan observation in
which this source falls. For a more precise value of Julian date
for this source, see the jdate entry in the PSC using
the pts_key index as a cross-reference.

| --- | Position Information | ||||
| 2 | designation | S | 17s | - |
Source designation formed from sexigesimal coordinates. This is the object sequence designation, or object "name" as specified by the IAU recommendations on source nomenclature. It is derived from the J2000 sexigesimal coordinates of the source and has the form HHMMSSSS+/-DDMMSSS, where HH are the hours of right ascension, MM the RA minutes and SSS are the deci-seconds of RA. DD are the degrees in declination, MM are DEC minutes and SS the declination seconds. Note that both the RA deci-seconds of time and DEC seconds of arc are truncated rather than rounded, per the IAU recommendation. The full naming convention for 2MASS All-Sky Release sources has the form "2MASX Jhhmmssss+ddmmsss[ABC...]", where "2MASX" indicates that the source is from the All-Sky XSC, "J" indicates the position is J2000, and the optional trailing letters are used to distinguish sources with otherwise duplicate names. The "2MASX J" prefix is not listed explicitly in the designation column. |

Right ascension (J2000 decimal deg) based on peak pixel. |

Galactic longitude (decimal deg) based on peak pixel.
Galactic coordinate for 2MASS source derived by precessing reconstructed ra
and dec to B1950, and performing rotational transformation into lII, bII coordinate system. This
coordinate should not be used as an astrometric reference because it has been rounded to 0.001
deg.
|
| 8 | glat | L | 7.3f | deg |
Galactic latitude (decimal deg) based on peak pixel.
Galactic coordinate for 2MASS source derived by precessing reconstructed ra
and dec to B1950, and performing rotational transformation into lII, bII coordinate system. This
coordinate should not be used as an astrometric reference because it has been rounded to 0.001

Sources are tested for contamination and/or confusion in the order given below, and once a flag is applied to the source, testing is stopped in that band.
