This publication describes the observations, data reduction, and data products in full detail.
All images are in fits format and the spectra are in encapsulated postscript format. All files are compressed with gzip.
Spectrum: The naturally weighted HI spectrum
Data Cube: The HI data cube, not primary beam corrected. Channels are in LSR velocity units. Brightness in Jy beam-1.
Column Density: The integrated HI intensity map, converted to units of HI column density (cm-2)
Moment 0: The integrated HI intensity map in Jy beam-1 km s-1 units
Moment 1: The intensity-weighted HI velocity map in units of km s-1
Moment 2: The Moment 2 map, a measure for the HI linewidth, in units of km s-1
na/ro: All images are available in natural or robust weighted versions. Natural (na) weighted data are more sensitive to surface brightness than robust (ro) weighted data. Robust weighted data, on the other hand, has better spatial resolution than natural weighted data.
HS117, KDG63, KKH37, DDO113, KKR25, KK77 were not detected in our HI survey.
