THE 1ST EXTREME-ULTRAVIOLET EXPLORER SOURCE CATALOG

The Extreme Ultraviolet Explorer(EUVE) has conducted an all-sky survey to locate and identify point sources of emission in four extreme ultr aviolet wavelength bands centered at approximately 100, 200, 400, and 600 angstrom. A companion deep survey of a strip along half the eclipt ic plane was simultaneously conducted. In this catalog we report the s ources found in these surveys using rigorously defined criteria unifor mly applied to the data set. These are the first surveys to be made in the three longer wavelength bands, and a substantial number of source s were detected in these bands. We present a number of statistical dia gnostics of the surveys, including their source counts, their sensitiv ities, and their positional error distributions. We provide a separate list of those sources reported in the EUVE Bright Source List which d id not meet our criteria for inclusion in our primary list. We also pr ovide improved count rate and position estimates for a majority of the se sources based on the improved methodology used in this paper. In to tal, this catalog lists a total of 410 point sources, of which 372 hav e plausible optical ultraviolet, or X-ray identifications, which are a lso listed.
