dc.descriptionThe Westerbork HALOGAS Survey: Data Release 1 (version 2) The Westerbork Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) Survey comprises deep neutral hydrogen (HI) 21-cm emission line observations of 24 nearby galaxies, along with ancillary data products such as deep optical imaging, radio continuum images, and single-dish HI data. This first data release (HALOGAS-DR1) provides the following HI data products in FITS format, for each of the 24 galaxies: High resolution (~15") data products Data cube: <galaxy_name>-HR-cube.fits Moment-0 (integrated intensity): <galaxy_name>-HR_mom0m.fits Column density: <galaxy_name>-HR_coldens.fits Moment-1 (average velocity): <galaxy_name>-HR_mom1m.fits Low resolution (~30") data products Data cube: <galaxy_name>-LR-cube.fits Moment-0 (integrated intensity): <galaxy_name>-LR_mom0m.fits Column density: <galaxy_name>-LR_coldens.fits Moment-1 (average velocity): <galaxy_name>-LR_mom1m.fits Moment maps were generated with the SoFiA source finding package. Changes from version 1 A substantial error was identified with the velocity axis of the HI cubes for NGC 4448, leading to a large bulk offset from the true systemic velocity of the galaxy. Version 2 corrects this error in the cubes and the corresponding moment-1 (average velocity) images for NGC 4448. The data products for all other galaxies are unmodified from version 1.
