b. 6x Extended Source Working Database/Catalog Column Descriptions

The 2MASS 6x Extended Source Working Database/Catalog (6x-XSWDB/XSC) contains 389 columns of information per source entry (most of which is photometry). Because extended sources are much more complicated than point sources, 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 6x-XSWDB/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 accordingto their basic function and utility.

Photometry algorithms and performance, "Large Aperture Photometry: Profile Fitting, Isophotal & Total Mags," are discussed in Section IV.5e. The information contained in the All-Sky Release Extended Source Catalog (XSC) FAQ and Primer, "How to Use the 2MASS XSC -- FAQ Sheet" (Section II.3b) is directly applicable to the 6x-XSWDB because 6x extended source processing used the same algorithms that were used for the Survey data.

Accessing the 6x-XSC
The 2MASS 6x-XSC is the subset of entries in the 6x-XSWDB that satisfy catalog selection criteria designed to produce a reliable list of extended source detections with only one measurement of objects detected multiple times. The 6x-XSC is not released as a separate table, like the All-Sky XSC, but is integrated into the 6x-XSWDB table. Entries in the 6x-XSWDB that constitute the 6x-XSC are identified by the cat column, and have a value of cat="1".
Note: If you are accessing the 6x-XSC with the IRSA/GATOR catalog query engine, you must select sources with cat="1" and you must change the reliability range to "A-F (All)" in the "Reliability Limit" dialog box. This second step is necessary because GATOR defaults to rel="A" selection, and the catalog selection rules are different than the reliability scoring rules, resulting in the inclusion in the 6x-XSC of a small fraction of sources that have reliability scoring lower than "A".

D. Miscellaneous Photometry and Characterization Measures

column	Parameter Name	View	Format	Units	Description
---	Quality and Star-Galaxy Discrimination Scores
65	rel	S	1s	-	Reliability flag. Single character flag that is related to the probability that the extraction is a valid detection of a near infrared source on the sky at the time of the observation, and that the source is resolved relative to the 2MASS point spread function. "A" - P>90% "B" - 80%<P<90% "C" - 70%<P<80% "D" - 50%<P<70% "E" - 20%<P<50% "F" - P<20% This flag does not provide information about the quality of the position or flux measurement. For that, users should refer to e_score, g_score, vc, cc_flg and positional and photometric uncertainties.
66	e_score	L	5.2f	-	extended score: 1(extended) < e_score < 2(point-like). See the FAQ: Star-Galaxy Separation: How do the E and G-scores work?
67	g_score	L	5.2f	-	galaxy score: 1(extended) < g_score < 2(point-like). See the FAQ: Star-Galaxy Separation: How do the E and G-scores work?
68	vc	L	2hd	-	visual verification score for source. The visual classification score gives the source type for those sources examined "by eye": -2 = unknown -1 = no verification (i.e., not examined) 1 = galaxy 2 = non-extended (e.g., star, double, triple, artifact) See Visual Inspection of Extended Sources
69	cc_flg	S	1s	-	indicates artifact contamination and/or confusion. The contamination/confusion flag indicates whether the source's photometry and position may be affected by artifacts of, or confusion with, nearby bright stars. The flag consists of a single character string. 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. The flag values indicate the source may be: A - Known artifacts z - In close promity to a large galaxy; these sources are usually junk X - Extraction is found within a 4" radius of a large (LGA) galaxy. Photometry is often truncated by scan edges. Refer to the Large Galaxy Atlas for accurate information for these sources. 0 - Default value -- not contaminated See Extended Source Confusion Flag
70	spos	S	5d	-	Number of scans covering the position of this extraction. This is computed during the WDB merging process, using boundaries of each scan that are great-circle interpolations connecting the 3-band coverage corners. Since actual scans "wiggle" slightly in RA due to telescope motions, the actual number of coverages for extractions near scan edges can differ from spos. A null value in this column indicates that the source was not included in the source merging process because of low reliability, or proximity to a scan edge.
71	sdet	S	5d	-	Total number of detections of this extraction in any band in this WDB table, in all scans covering its position, determined during the WDB merging processing. It is possible to have sdet > spos for extractions because extended sources may have in-scan duplicate extractions in the Atlas Image overlap regions, and near scan edges because of the approximations used to determine spos. A null value in this column indicates that the source was not included in the source merging process because of low reliability, or proximity to a scan edge.
72	gcntr	S	5d	-	Unique identification number of the record in the Merged Extended Source Information table corresponding to the merged "group" containing this extraction. The merged "group" contains the combined position and brightness information for all extractions falling within ~5" of each other in the WDB. In confused cases where this extraction appears in more than one group (gcnf>1), the indicated group is the one to which this extraction lies closest. A null value in this column indicates that the source either that the position of this extraction was observed only once, or it was not included in the source merging process because of low reliability, or proximity to a scan edge.
73	gcnf	S	1d	-	Merging confusion flag. Single digit flag that indicates whether this extraction was associated with more than one group during the WDB merging process. "0,1" - Extraction associated with only one group. "2,3" - Extraction associated with more than one group. Group indicated in the gcntr column is one whose center lies closest to the position of this extraction. "null" - Extraction was observed only once, or was not included in the source merging process because of low reliability, or proximity to a scan edge.

The fiducial band for the total Kron photometry and 20mag/sq." isophotal photometry is the K band, and for the 21mag/sq." isophotal photometry it is the J band.
