FUV to FIR phot. of massive galaxies in SDSS Stripe 82

We present a comprehensive catalog of panchromatic photometry, covering 17 bands from the far-ultraviolet to 500{mu}m, for 2685 low-redshift (z=0.01-0.11), massive (M_*_>10^10^M_{sun}_) galaxies selected from the Stripe 82 region of the Sloan Digital Sky Survey, one of the largest areas with relatively deep, uniform observations over a wide range of wavelengths.

Taking advantage of the deep optical coadded images, we develop a hybrid approach for matched-aperture photometry of the multiband data. We derive robust uncertainties and upper limits for undetected galaxies, deblend interacting/merging galaxies and sources in crowded regions, and treat contamination by foreground stars. We perform spectral energy distribution fitting to derive the stellar mass, SFR, and dust mass, critically assessing the influence of flux upper limits for undetected photometric bands and applying corrections for systematic uncertainties based on extensive mock tests.
