Abstract:
    Using the powerful Earth-occultation technique, long-term, nearly
    continuous monitoring of the entire low-energy gamma-ray sky is now
    possible with the advent of BATSE, the Burst and Transient Source
    Experiment on board the Compton Gamma Ray Observatory (CGRO). In this
    paper, we present a catalog of 34 moderately strong gamma-ray sources
    measured by BATSE. It consists of 0.03 - 1.8 MeV photon spectra
    averaged over weeks and months, and light curves of the 35 - 200 keV
    flux, with 1 day resolution, covering the first three phases of the
    CGRO mission (1991 May through 1994 October). This database contains a
    complete record of {~}1200 daily source count rates in 14 energy
    channels along with the corresponding Poisson and systematic errors.
