VizieR Online Data Catalog: The GALFA-HI survey data release 2 (Peek+, 2018)
Abstract
The GALFA-HI survey is conducted with the William E. Gordon Arecibo Observatory 305m telescope, located south of Arecibo Puerto Rico. This survey owes its name to the instrument with which it was conducted, the ALFA, a 7-beam array of heterodyne detectors, sensitive from 1225 to 1525MHz.
The observational strategy of DR2 is one of the significant differences from DR1 (Peek+ 2011ApJS..194...20P); see section 2.2. Region North-1 was included in DR1, but otherwise all of the Arecibo HI data presented in this work are new. (3 data files).- Publication:
