Arecibo legacy fast ALFA survey III.
Listed in IVOA Registry (Virtual Observatory)
We present the first installment of HI sources extracted from the Arecibo Legacy Fast ALFA (ALFALFA) extragalactic survey, initiated in 2005.
Description
Sources have been extracted from three-dimensional spectral data cubes exploiting a matched filtering technique and then examined interactively to yield global HI parameters. A total of 730 HI detections are cataloged within the solid angle 11h44<RA(J2000.0)<14h00 and +12{deg}<DE(J2000.0)<+16{deg} and redshift range -1600km/s<cz<18000km/s.
In comparison, the HI Parkes All-Sky Survey (HIPASS, Meyer et al. 2004, Cat. VIII/73) detected 40 HI signals in the same region. Optical counterparts are assigned via examination of digital optical imaging databases.
