a. The Extended Source Processor

Table 1. XSC Parameters

The XSC contains over 300 columns of information per source, most of which is photometric data. The columns are described in the subtables below. We have separated the columns according to their basic function and utility.

i. Name and Position Information

Parameter Name	View	Format	Units	Description
jdate	L	13.4f	jdate	Julian Date.
Position Information
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.

id_flg	L	1hd	-	type/galaxy ID flag (0=non-catalog, 1=catalog, 2=LCSB). This flag indicates the extended source catalog type as follows: 0 = extended source not found in another catalog 1 = extended source is found in galaxy catalog (ID found in id_cat field) 2 = LCSB (Low Central Surface Brightness) source
id_cat	L	20s	-	matched galaxy's catalog name.
fg_flg	L	6s	-	flux-growth convergence flag.
blk_fac	L	1hd	-	LCSB blocking factor (1, 2, 4, 8).
dup_src	L	1hd	-	has duplicate source extractions (overlap areas).
use_src	L	1hd	-	this extraction of source is to be used in catalog.
prox	L	4.3f	arcsec	distance in arcsec to nearest catalog source within 9.9".
pxpa	L	5.1f	deg	angle (E of N) to nearest catalog source within 9.9".
pxcntr	L	9d	-	cntr of nearest catalog source within 9.9".
dist_edge_ns	L	8.1f	arcsec	distance to nearest north or south full-coverage scan edge.
dist_edge_ew	L	6.1f	arcsec	distance to nearest east or west full-coverage scan edge.
dist_edge_flg	L	2s	-	flag indicating which edges ([n|s][e|w]) are nearest to src.
pts_key	L	9d	-	key to point source data DB record. If the source has point source data (i.e. it is not an LCSB), this field will be set to the key of the record in the point source table containing the point source data. The point source data will also have the same date, hemisphere, scan, id keys.
mp_key	L	5d	-	key to minor planet prediction DB record. If a minor planet (asteroid) is predicted at this src's position, the field is set to the key of the record containing the minor planet prediction data (see the minor planet tbls). The minor planet data will also have the same date, hemisphere, scan, id keys.
night_key	L	4d	-	key to night data record in "scan DB". This field is set to the key of the record containing the corresponding night data in the night data table. The records will also have the same date and hemisphere keys.
scan_key	L	6d	-	key to scan data record in "scan DB". This field is set to the key of the record containing the corresponding scan data in the scan data table. The records will also have the same date, hemisphere, scan keys.
coadd_key	L	7d	-	key to coadd data record in "scan DB". This field is set to the key of the record containing the corresponding J, H, and K band coadd data in the coadd data table. The records will also have the same date, hemisphere, scan, coadd keys.
hemis	L	1s	-	hemisphere (N/S) of observation.
date	L	yymmdd	-	observation date.
scan	L	3hd	-	scan number (unique within date).
coadd	L	03hd	-	3-digit coadd number (unique within scan).
id	L	6d	-	source ID number (unique within scan, coadd).
x_coadd	L	6.1f	arcsec	x (cross-scan) position (coadd coord.).
y_coadd	L	6.1f	arcsec	y (in-scan) position (coadd coord.).
j_subst2	L	6.1f	-	J residual background #2 (score).
h_subst2	L	6.1f	-	H residual background #2 (score).
k_subst2	L	6.1f	-	K residual background #2 (score).
j_back	L	6.1f	-	J coadd median background.
h_back	L	6.1f	-	H coadd median background.
k_back	L	6.1f	-	K coadd median background.
j_resid_ann	L	7.3f	DN	J residual annulus background median.
h_resid_ann	L	7.3f	DN	H residual annulus background median.
k_resid_ann	L	7.3f	DN	K residual annulus background median.
j_bndg_per	L	5d	arcsec	J banding Fourier Transf. period on this side of coadd.
j_bndg_amp	L	6.3f	DN	J banding maximum FT amplitude on this side of coadd.
h_bndg_per	L	5d	arcsec	H banding Fourier Transf. period on this side of coadd.
h_bndg_amp	L	6.3f	DN	H banding maximum FT amplitude on this side of coadd.
k_bndg_per	L	5d	arcsec	K banding Fourier Transf. period on this side of coadd.
k_bndg_amp	L	6.3f	DN	K banding maximum FT amplitude on this side of coadd.
j_seetrack	L	4.1f	-	J band seetracking score.
