COMMENT
COMMENT  This image was created for SINGG - the Survey for Ionization in
COMMENT  Neutral Gas Galaxies.  SINGG is an H-alpha and R band CCD imaging
COMMENT  survey of galaxies selected from the HI Parkes All Sky Survey (HIPASS;
COMMENT  Meyer et al. 2004, MNRAS).  This image comprises part of SINGG Release
COMMENT  1.0 (SR1.0).  Details of the SINGG survey and SR1.0 can be found in
COMMENT  Meurer et al (2006, ApJS, in press; astro-ph/0604444).  The reduction
COMMENT  of the SR1.0 images includes basic CCD processing (bias level
COMMENT  subtraction, bias image subtraction, flat fielding), image
COMMENT  registration, combining of images with CR rejection, and flux
COMMENT  calibration.  Some images obtained with the 6568/28 filter had a model
COMMENT  of an extended diffuse scattered-light feature subtracted.  Continuum
COMMENT  (usually R band) subtraction is performed after convolving the image
COMMENT  with the best seeing with a kernel to match that having the worst
COMMENT  seeing.  Details of the data reduction and analysis can be found in
COMMENT  Meurer et al. (2006).  Details of the SINGG survey can be found at
COMMENT  http://sungg.pha.jhu.edu/ .
COMMENT
COMMENT  The World Coordinate System (WCS) in the images were set by matching
COMMENT  positions of roughly 100 sources in the R or continuum image to the
COMMENT  U.S. Naval Observatory A2.0 database yielding a typical rms accuracy of
COMMENT  0.4 arcsec (one pixel).  The photometric calibration of the images was
COMMENT  performed by observations of spectrophotometric standards, yielding
COMMENT  an estimated accuracy of 0.02 mag, except for images obtained with the
COMMENT  6568/28 filter, which have an estimated photometric accuracy of 0.04
COMMENT  mag.
COMMENT
COMMENT  SR1.0 represents the best effort reduction and analysis by the SINGG
COMMENT  team.  The data is made available to the public free of charge on an
COMMENT  *as is* basis without warranty of any kind, either expressed or
COMMENT  implied.  If you use SINGG images in your research please make the
COMMENT  following acknowledgement in any publications that result: "This
COMMENT  research made use of images provided by the Survey for Ionization in
COMMENT  Neutral Gas Galaxies (Meurer et al. 2006) which is partially supported
COMMENT  by the National Aeronautics and Space Administration (NASA)."
