 Notes for designation: 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 HHMMSSS+/-DDMMSS, 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.

20 j_m J selected "default" magnitude mag decimal(5,3) y 1 y y y
 Notes for j_m: This is the selected "default" magnitude for each band. The first choice for the [jhk]_m values are the mags in each band at 20 mag/sq.arcsec w/K fiducial circular aperture ([jhk]_m_k20fc), indicated by [jhk]_mtype values of 0. If, however, the K band mag in this group is > 14.0 (including negative flux or no mag found), all 3 [jhk]_m values will be the mags at 21 mag/sq.arcsec w/J fiducial circular aperture ([jhk]_m_j21fc) and the flags [jhk]_mtype are set to 1. If any one of chosen set of "default" mags is > 99, indicating no mag found, the DB entry for that "default" mag will be set to NULL.
Thus, the [jhk]_mtype flags will indicate the source of the "default" mags and sigmas as follows:
0: [jhk]_m_k20fe values
1: [jhk]_m_j21fe values
21 h_m H selected "default" magnitude mag decimal(5,3) y 1 y y y

If any one of chosen set of "default" mags is > 99, indicating no mag found, the DB entry for that "default" mag will be set to NULL.

These uncertainties are the quadratic combination of the source extraction uncertainites, the photometric zero point offset uncertainties from the night during which the source was observed ([jhk]_zperr from the "Scan Data" table), and the residual flat-fielding errors (estimated to be 0.005 mags for all bands). The simple measurement uncertainty can be recovered by backing out the contributions of the photometric zero point uncertainty and the flat-fielding uncertainty from the values listed.

 Notes for contam_flg: The stellar and artifact contamination flag provides information about whether the extended source brightness estimate may be contaminated by superimposed point sources, or possible confusion with image artifacts generated by nearby bright stars (e.g. latent images, diffraction spikes, confusion halos and ghosts, and stripes). The value of the flag is given by: (stellar_contam_flg*10) + artflag. "Stellar_contam_flg"=0 if there is no contamination by superimposed point sources and =1 if there is. "Artflag" is the key to possible bright star artifact contamination and has the value: 0=no contamination, 1=dichroic glint, 2=latent or persistence image, 3=diffraction spike, 4=confusion in wings of a bright star.

386 j_h default J-H mag color mag decimal(5,3) y 1 n y y
 Notes for j_h: Magnitude colors are calculated using the [jhk]_m default mags and sigmas for the extended sources and the optical mags [br]_m_opt in the associated point source entry. If one of the mags used in a color calculation is NULL, the color value is an upper or lower limit. (Color limits are NOT calculated when both mags are NULL.)
387 j_h_sig sigma for J-H mag color mag decimal(4,3) y 0 n y y
 Notes for j_h_sig: For colors having detections in both bands, the color mag sigma values are the root-sum-square of the two mag sigmas. If one of the mags used in the calculation is NULL, the color sigma is the other band's mag sigma.
388 h_k default H-K mag color mag decimal(5,3) y 1 n y y
 Notes for h_k: Magnitude colors are calculated using the [jhk]_m default mags and sigmas for the extended sources and the optical mags [br]_m_opt in the associated point source entry. If one of the mags used in a color calculation is NULL, the color value is an upper or lower limit. (Color limits are NOT calculated when both mags are NULL.)
389 h_k_sig sigma for H-K mag color mag decimal(4,3) y 0 n y y
 Notes for h_k_sig: For colors having detections in both bands, the color mag sigma values are the root-sum-square of the two mag sigmas. If one of the mags used in the calculation is NULL, the color sigma is the other band's mag sigma.
390 j_k default J-K mag color mag decimal(5,3) y 1 n y y
 Notes for j_k: Magnitude colors are calculated using the [jhk]_m default mags and sigmas for the extended sources and the optical mags [br]_m_opt in the associated point source entry. If one of the mags used in a color calculation is NULL, the color value is an upper or lower limit. (Color limits are NOT calculated when both mags are NULL.)

 Notes for j_k_sig: For colors having detections in both bands, the color mag sigma values are the root-sum-square of the two mag sigmas. If one of the mags used in the calculation is NULL, the color sigma is the other band's mag sigma.

 Notes for r_k: Magnitude colors are calculated using the [jhk]_m default mags and sigmas for the extended sources and the optical mags [br]_m_opt in the associated point source entry.
