Abstract:
We introduce the Survey for Ionization in Neutral Gas Galaxies
(SINGG), a census of star formation in HI-selected galaxies. The
survey consists of Hα and R-band imaging of a sample of 468
galaxies selected from the HI Parkes All Sky Survey (HIPASS). The
sample spans three decades in HI mass and is free of many of the
biases that affect other star-forming galaxy samples. We present
the criteria for sample selection, list the entire sample, discuss
our observational techniques, and describe the data reduction and
calibration methods. This paper focuses on 93 SINGG targets whose
observations have been fully reduced and analyzed to date.

Note (1): Flags as follows:
d = there is flux outside of the region measured with elliptical aperture.
dd = flux exterior to the elliptical apertures is >10% of the total flux.
# = the Hα flux was measured with just small apertures centered
on the obvious HII regions instead of the standard method.
Cases which are measured with this technique, have invalid Reff,
R90 in which case the appropriate columns are left NULL.
S = the source extends close to or beyond the frame boundary.

effective surface brightness.
Note (3): Corrected for Galactic extinction and [NII] contamination. In
units of erg/cm2/s.
