The Arecibo Legacy Fast ALFA survey. I. Science goals, survey design, and strategy

TL;DR: The ALFALFA project as discussed by the authors uses a two-pass, minimum intrusion, drift scan observing technique that samples the same region of sky at two separate epochs to aid in the discrimination of cosmic signals from noise and terrestrial interference.
