| name | type | length | unit | ucd | description |
| objID | bigint | 8 | | | Unique SDSS identifier composed from [skyVersion,rerun,run,camcol,field,obj]. |
| ra | float | 8 | deg | | SDSS right ascension, J2000 |
| dec | float | 8 | deg | | SDSS declination, J2000 |
| has_wise_phot | bit | 1 | | | Does WISE forced photometry exist for this source? |
| x | real | 4 | | | FITS pixel coordinate in the unWISE tile |
| y | real | 4 | | | FITS pixel coordinate in the unWISE tile |
| treated_as_pointsource | bit | 1 | | | Was this source treated as a point source for photometry purposes? |
| coadd_id | char | 8 | | | unWISE tile identification, RRRR[pm]DDD, RRRR = int(10 * RA), DDD = int(10 * Dec), [pm] = sign(Dec), eg 2052p620 |
| w1_nanomaggies | real | 4 | Vega mag | | W1 flux. Fluxes are presented in the Vega system, NOT AB. 1 nmgy means Vega mag 22.5 |
| w1_nanomaggies_ivar | real | 4 | 1/(Vega mag)^2 | | Inverse-variance uncertainty for w1_nanomaggies |
| w1_mag | real | 4 | Vega mag | | W1 magnitude. w1_nanomaggies converted to (Vega) magnitudes. |
| w1_mag_err | real | 4 | Vega mag | | W1 magnitude uncertainty |
| w1_prochi2 | real | 4 | | | Profile-weighted chi-squared (goodness of fit) |
| w1_pronpix | real | 4 | | | Profile-weighted number of WISE exposures in coadd |
| w1_profracflux | real | 4 | | | Profile-weighted fraction of flux coming from other sources; blendedness measure. |
| w1_proflux | real | 4 | | | Profile-weighted flux coming from other sources |
| w1_npix | real | 4 | | | Number of pixels used in fit |
| w2_nanomaggies | real | 4 | Vega mag | | W2 flux. Fluxes are presented in the Vega system, NOT AB. 1 nmgy means Vega mag 22.5 |
| w2_nanomaggies_ivar | real | 4 | 1/(Vega mag)^2 | | Inverse-variance uncertainty for w2_nanomaggies |
