Abstract:
Star formation is arguably the most important physical process in the
cosmos. It is a fundamental driver of galaxy evolution and the
ultimate source of most of the energy emitted by galaxies. A correct
interpretation of star formation rate (SFR) measures is therefore
essential to our understanding of galaxy formation and evolution.
Unfortunately, however, no single SFR estimator is universally
available or even applicable in all circumstances: the numerous
galaxies found in deep surveys are often too faint (or too distant) to
yield significant detections with most standard SFR measures, and
until now there have been no global, multi-band observations of nearby
galaxies that span all the conditions under which star-formation is
taking place. To address this need in a systematic way, we have
undertaken a multi-band survey of all types of star-forming galaxies
in the local Universe. This project, the Star Formation Reference
Survey (SFRS), is based on a statistically valid sample of 369 nearby
galaxies that span all existing combinations of dust temperature, SFR,
and specific SFR. Furthermore, because the SFRS is blind with respect
to AGN fraction and environment it serves as a means to assess the
influence of these factors on SFR. Our panchromatic global flux
measurements (including GALEX FUV+NUV, SDSS ugriz, 2MASS JHKs, Spitzer
3-8um, and others) furnish uniform SFR measures and the context in
which their reliability can be assessed. This paper describes the SFRS
survey strategy, defines the sample, and presents the multi-band
photometry collected to date.

Note (1): Coordinates are based on Spitzer/IRAC imaging.
Note (2): Quality distances from R.B. Tully (priv. comm.) are given with
1σ error estimates. All other distances are derived from the PSCz
velocities after correcting for local bulk flow as described in Sec. 3.1.
Note (3): L60 is a monochromatic 60um luminosity calculated for purposes of
sample selection. The more useful L(TIR) is given in Table 7.
Note (4): Weights are the ratio of the total number of PSCz galaxies within a
given bin to the number of SFRS sample galaxies taken from that same bin,
subject to the area restrictions noted in Sec. 2.
Note (5): Axial ratios were measured directly from the IRAC mosaics using
SExtractor and are estimated to be accurate to 0.05 (1σ).
Note (6): Morphological T types and B-band Milky Way extinction (in magnitudes,
estimated from the 100um dust maps) were taken from the PSCz catalog
(Saunders et al., 2000, Cat. VII/221), except as noted.

Note (11): The MIPS 24um photometry has been aperture corrected using the
correction factors listed in Table 8. The uncertainties in total 24um flux
densities are dominated by the uncertainty in the absolute calibration,
which is estimated as 4-8% according to the MIPS Instrument Handbook,
version 2. Where upper limits are given, the photometry is from IRAS with
quality flag = 1.
Note (12): Notes as follows:
b = IRAS flux density (MIPS not available), typical uncertainties are 10-20%
c = OJ 287 is highly variable. Flux densities here are from IRAS survey
coadds (Impey & Neugebauer, 1988AJ.....95..307I 1988AJ.....95..307I), but many more
measurements exist in the literature.
d = IRAS flux densities taken from Rice et al. 1988, Cat. VII/109.
e = Measurement taken from Dale et al. (2005ApJ...633..857D 2005ApJ...633..857D).
