Description:
This catalog of the EUVE Science Archive has been constructed based on information provided by personnel of the Center for Extreme-Ultraviolet Astrophysics (CEA), and is made available in the current EUVEMASTER database table. Most of the information in the catalog is also in the headers of the FITS files. The HEASARC now has nearly all of the 1378 pointed EUVE Deep Survey/Spectrometer (DS/S) datasets that were processed by CEA until its closing in March 2001. There are a small number of observations that were made in the year 2000 for which the HEASARC does not currently have the corresponding datasets. Notice that this catalog does not contain entries corresponding to EUVE observations in scan mode or where the files received by the HEASARC were not of the normal image or events type. This is the 7th (and possibly final) version of the EUVEMASTER database, last updated in June 2001. This catalog has been constructed based on information provided by staff members of the Center for Extreme-Ultraviolet Astrophysics (CEA) in Berkeley, CA, whose help is gratefully acknowledged.

Description:
The Extreme Ultraviolet Explorer (EUVE) has been detecting EUV sources since its launch in June 1992. Positions of 540 sources have been made available to the community by the EUVE team. We have extracted 7'x7' images centered on these 540 EUVE sources from the Space Telescope Science Institute digitized sky archives. We present these images as mosaic finder charts to aid observers trying to identify EUVE sources, or to characterize known sources.

Publisher:
NASA/GSFC HEASARC
Description:
The Second Extreme Ultraviolet Explorer (EUVE) Right Angle Program (RAP) Catalog contains information on the detection of 235 extreme ultraviolet (EUV) sources, of which 169 are new detections, using the EUVE's RAP data. This catalog included observations made since the first EUVE RAP catalog (1994 January) and covered 17% of the sky. The EUVE RAP used the all-sky survey telescopes (also known as "scanners"), which were mounted at right angles to the Deep Survey and Spectrometer instruments, to obtain photometric data in four wavelength bands centered at 100 Angstroms (Lexan/B), 200 A (Al/Ti/C), 400 A (Ti/Sb/Al or Dagwood), and 550 A (Sn/SiO). The EUVE RAP2 Catalog contains source count rates and probable source identifications from the available catalogs and literature. The source distribution is similar to previous EUV catalogs with 2% early-type stars, 45% late-type stars, 8% white dwarfs, 6% extragalactic objects, 24% with no firm classification, and 15% with no optical identification. This database was created at the HEASARC in May 2002 based on the ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/AJ/117/2466">CDS Catalog J/AJ/117/2466</a> and is derived from Tables 2, 3, and 4 the published paper.

Description:
The Third Extreme Ultraviolet Explorer (EUVE) Right Angle Program (RAP) Catalog contains information on the detection of 76 extreme ultraviolet (EUV) sources, of which 63 are new detections, using the EUVE's RAP data. This catalog concentrates on observations made in the last years of the RAP, 1999 and 2000, with a sky coverage of 7% of the sky. The EUVE RAP used the all-sky survey telescopes (also known as "scanners"), which were mounted at right angles to the Deep Survey and Spectrometer instruments, to obtain photometric data in four wavelength bands centered at 100 Angstroms (Lexan/Boron or "Lexan"), 200 A (Al/Ti/C or "Al/C"), 400 A (Ti/Sb/Al or "Dagwood"), and 600 A (Sn/SiO or "Tin"). The EUVE RAP3 Catalog contains source count rates and probable source identifications from the available catalogs and literature. The source distribution is similar to previous EUV catalogs with 5 (8%) early-type stars, 23 (37%) late-type stars, 1 (2%) white dwarf, 1 (2%) cataclysmic variable, 4 (6%) extragalactic objects, 22 (35%) with no firm classification, and 7 (11%) with no optical identification. This final RAP Catalog, combined with the EUVE All-Sky Survey, the Lampton et al. (1997, ApJS, 108, 545) Faint EUV Source List, and previous RAP Catalogs, brings the total number of EUV sources to nearly 1200. This table was created by the HEASARC in September 2011 based on an ASCII version of Table 1 from the reference paper which was obtained from the AJ web site.

EUVE Right Angle Program, 1st Catalog
Short Name:
EUVERAP1
Date:

Publisher:
NASA/GSFC HEASARC
Description:
This table contains the detections of 114 extreme-ultraviolet (EUV; 58 - 740 Angstrom) sources, of which 99 are new serendipitous sources, based on observations covering approximately 8% of the sky which were made with the imaging telescopes on board the Extreme Ultraviolet Explorer (EUVE) during the Right Angle Program (RAP). 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.

8. EUVE Second Source Catalog

Title:
EUVE Second Source Catalog
Short Name:
EUVE/2
Date:
07 Mar 2025
Publisher:
NASA/GSFC HEASARC
Description:
This is the 2nd Catalog of EUV objects detected by the Extreme Ultraviolet Explorer (EUVE) and published by Bowyer et al. in 1996 (ApJS, 102, 129). The data include (i) all-sky survey detections from the initial 6-months scanner survey phase, (ii) additional scanner detections made later during specially programmed observations designed to fill in low-exposure sky areas of the initial survey, (iii) sources detected with deep-survey telescope observations along the ecliptic plane, (iv) objects detected by the scanner telescopes during targeted spectroscopy observations, and (v) other observations. Plausible optical, X-ray, radio, and/or UV identifications are available for about 65% of the EUV sources. The EUVE all-sky survey detections (indicated by detect_mode = EASS in this catalog) comprise 514 detected EUV-emitting objects, the deep-survey detections (indicated by detect_mode = DS in this catalog) comprise 35 detected objects, and the sources detected during other phases of the mission (indicated by detect_mode = OTHER in this database) comprise 188 detected objects. Notice that 3 deep survey objects were also detected in the all-sky survey. Most of the sources detected in the other phases principally comprise those detected in deep exposures with the scanner telescopes as part of the Right Angle Program through December 24, 1994, or in long exposures with the deep survey instrument. Because these latter objects were observed with a variety of instruments and exposure strategies, the flux limits and detection thresholds vary over a wide range, and the Bowyer et al. reference should be consulted for more details. Some of the EUV sources have alternative cross-identifications at other wavelengths suggested for them. Notice that, in such cases, we have followed the original catalog and listed separate entries for each alternate identification. For example, the EUV-emitting object EUVE J1147+202 is listed twice, once with the suggested ID of DQ Leo, and a second time with the suggested ID of BD +21 2357. Thus, there are 801 entries in this database corresponding to 737 unique EUV sources. This is a service provided by NASA HEASARC .
