This photometry was published in Dale et al. 2017:

 Global fluxes WITHOUT Milky Way foreground extinction corrections applied.

 -1 implies that the flux listed is a 5sigma upper limit.
 -2 implies that the flux listed is likely a lower limit due to saturation issues in M82.
 
Apertures are those used in Dale+2007 (SINGS Spitzer), Dale+2009 (LVL Spitzer), Dale+2012 (KINGFISH Herschel).  Aperture corrections are described in those publications.

ugriz are from SDSS photometry.  12um is from WISE.

BVRcIc fluxes are largely those from Dale+2007 but bootstrap-calibrated via foreground stars and Pan-STARRS1.  All details are explained in Dale+2017.

Nomenclature for data column headers:
S    --> Spitzer (except 850S implies SCUBA).
H    --> Herschel
W    --> Wise
20cm --> VLA

The last 4 columns stem from Tom Jarrett's "total" WISE fluxes.  I've added them for completeness, but beware that only my W3 12um fluxes in Column 20 utilize our canonical apertures; Jarrett's flux densities incorporate an extrapolation of the measured surface brightness profiles to 3 disk scale lengths beyond the last measurable isophote.

As explained on the 2nd line of each file, all fluxes are in Jy except for FUV, NUV, and 20cm.
