ALFALFA Survey Summary

The Arecibo Legacy Fast ALFA (ALFALFA) Survey used the seven-horn Arecibo L-band Feed Array (ALFA) to map nearly 7000 square degrees of high Galactic latitude sky accessible to the Arecibo telescope over ∼4400 nighttime hours between 2005 and 2011. ALFALFA was conducted as a “blind” survey: at each position, the entire frequency range from 1335-1435 MHz, corresponding to heliocentric velocities -2000 < cz < 18000 km/s, was searched for line emission.

The ALFALFA survey was intended to cover two sky areas at high Galactic latitude, one in the northern Galactic hemisphere 07h30m < R.A. < 16h30m, 0 < Dec. < +36 deg and one in the southern hemisphere, 22h < R.A. < 03h, 0 < Dec. < +36 deg. For various practical reasons, the final sky area, depicted in Figure 1 of Haynes et al . (2018) and in Figure 1 of Jones et al. (2018), is somewhat reduced near the edges.
