These data were obtained using the survey scanners and the Deep Survey instrument during the first year of the spectroscopic guest observer phase of the mission, from January 1993 to January 1994. The data set consists of 162 discrete pointings whose exposure times are typically two orders of magnitude longer than the average exposure times during the EUVE all-sky survey. Based on these results, the authors expect that EUVE will serendipitously detect approximately 100 new EUV sources per year, or about one new EUV source per 10 square degrees, during the guest observer phase of the EUVE mission. New EUVE sources of note include one B star and three extragalactic objects. The B star (HR 2875, EUVE J0729 - 38.7) is detected in both the Lexan/B (approximately 100 A) and Al/Ti/C (approximately 200 A) bandpasses, and the detection is shown not to be a result of UV leaks. The authors suggest that they are detecting EUV and/or soft x rays from a companion to the B star. Three sources, EUVE J2132+10.1, EUVE J2343-14.9, and EUVE J2359-30.6 are identified as the active galactic nuclei MKN 1513, MS2340.9-1511, and 1H2354-315, respectively. Some of the EUV sources have two or more alternative source identifications suggested for them in this catalog. Notice that, in such cases, the HEASARC has followed the structure of the original catalog as given in Table 2 of the reference paper, and lists separate entries for these alternative identifications. Thus, there are 152 entries in this database table, corresponding to 114 EUV sources. The characteristics of the 6 EUVE filters are listed in Table 1 of the reference paper (q.v.). This table was created by the HEASARC in February 2013 based on an electronic version of Table 2 from the reference paper which was supplied by Damian Christian (many thanks, Damian!) and extensively edited by the HEASARC, mostly to conform with the printed version. In 4 cases, the printed table was clearly incorrect, and a trailing 'B' from the alt_id_name was transposed to the type field. We have corrected these errors thus: <pre> Printed table As corrected in this table alt_id_name type alt_id_name type HD 22468 B ? HD 22468 B ? IDS 04199+1543 B ? IDS 04199+1543 B ? HD 29763 B ? HD 29763 B ? IDS 05264-0341 B ? IDS 05264-0341 B ? </pre> Because of the amount of hand-editing which was done, the user should treat the contents of this table with some caution and should cross-check its contents with the printed table.
