The WSRT HALOGAS Survey: The Sample

The HALOGAS Sample

As of early June 2009, the full HALOGAS survey has been approved! We list here the full sample. Galaxy parameters are from the Tully (1988) catalog, except for the rotational velocity which is from Hyperleda, and the adopted distance, which was determined and tabulated in the Pilot Paper.

The following targets were part of the Pilot Survey, which was approved for the semester 2009A: UGC 2082; NGC 672; NGC 925; and NGC 4565. In a few other cases, archival or previously published data will be utilized. The others were observed starting in the semester 2009B. Observations were completed in 2013.
