A1: Large-Area Sky Survey Instrument
The A1, or Large-Area Sky Survey (LASS) instrument, covered the 0.25—25 keV energy range, using seven large proportional counters. It was designed, operated, and managed at the Naval Research Laboratory (NRL) under the direction of Principal Investigator Dr. Herbert D. Friedman, and the prime contractor was TRW. The HEAO A-1 X-Ray Source Catalog included 842 discrete X-ray sources.

On which the Prince of Glory died,
My richest gain I count but loss,
And pour contempt on all my pride.”
