WISE photometry of sources in the SDSS catalogs

There are three versions of the catalogs:

sdss-dr10d
Uses the catalog from the SDSS-DR10 release. This is the version described in Lang, Hogg & Schlegel (2016).
sdss-dr13
Uses the catalog from the SDSS-DR13 release (which was still private to the SDSS collaboration at the time the paper was published).
eboss
The version used for targeting of the SDSS-IV/eBOSS survey, like sdss-dr13 but with only W1/W2.

Code can be found here: https://github.com/dstndstn/unwise-sdss-phot.

Contents:

sdss-dr10d-fields.fits
A table of SDSS fields for which forced photometry exists.
sdss-dr10d-tiles.fits
A table of WISE coadd tiles for which forced photometry exists.
specmatch-dr10.fits
SDSS DR10 spectra matched to our WISE photomtery. This is the DR10 specObj file augmented with our sdss-dr10d photometry for matching rows.
sdss-dr10d-pobj/
Our WISE photometry results, in files that are row-by-row parallel to the SDSS DR10 photoObj files. The directory structure follows the same pattern too: %(run)i/%(camcol)i/photoWiseForced-%(run)06i-%(camcol)i-%(field)04i.fits.
sdss-dr10d-phot/
Our WISE photometry results, in files corresponding to WISE coadd tiles. These include SDSS sources within the tile, plus a margin. The same SDSS object may appear in multiple tiles. The filename is based on the WISE tile name, which encodes an approximate RA, Dec center; phot-RRRR[pm]DDD.fits is the tile centered at roughly RRR.R degrees RA, DD.D degrees Dec.
sdss-dr10d-SEDs
"I just want RA,Dec, and the SDSS and WISE SEDs." Reasonable enough request! See the description below for details.
sdss-dr10d-{phot,pobj}/md5sums.txt
Checksums for all files. Pro tip: you could edit this file to produce a "wget" script, if you were so inclined.
sdss-dr13-* and eboss-
Same as for sdss-dr10d. The equivalent of sdss-dr10d-tiles.fits is named {sdss-dr13,eboss}-atlas.fits.
specmatch-dr12.fits
SDSS DR12 spectroscopy matched to our sdss-dr13 results.

See Appendix A of Lang, Hogg & Schlegel (2016) for a description of the catalog contents.

The SED tables, one per SDSS run+camcol, contain

Column number Column name Data type
1raD
2decD
3pointsourceL
4w1_nanomaggiesE
5w1_nanomaggies_ivarE
6w2_nanomaggiesE
7w2_nanomaggies_ivarE
8w3_nanomaggiesE
9w3_nanomaggies_ivarE
10w4_nanomaggiesE
11w4_nanomaggies_ivarE
12sdss_flux5E
13sdss_flux_ivar5E

Where "pointsource" = SDSS point source or treated_as_pointsource, "sdss_flux" = SDSS PSF flux for "pointsource" objects, "cmodelflux" otherwise.
