PROBES. I. A Compendium of Deep Rotation Curves and Matched Multiband Photometry

Abstract

Abstract We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them. PROBES rotation curves originally extracted from Hα long-slit spectra and aperture synthesis H i (21cm) velocity maps typically extend out to a median 2 R e (or 1 R 23.5,r ). Our uniform photometry takes advantage of GALEX, DESI-LIS, and WISE images and the software AutoProf to yield multiband azimuthally averaged surface brightness profiles that achieve depths greater than 25 mag arcsec−2 (FUV, NUV), 27 mag arcsec−2 (g, r), and 26 mag arcsec−2 (z, W1, and W2). With its library of spatially resolved profiles and an extensive table of structural parameters, the versatile PROBES data set will benefit studies of galaxy structure and formation.
