Second EUVE Catalogues (Bowyer+, 1996-99)

Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

ADC_Keywords: Surveys ; Ultraviolet; X-ray sources
Mission_Name: EUVE
Keywords: catalogs - stars: late-type - ultraviolet emission
Description:
The Extreme Ultraviolet Explorer satellite was launched on
June 7, 1992 from Cape Canaveral, Florida on a Delta II rocket.
The payload contains three EUV scanning telescopes equipped with
imaging detectors as well as a Deep Survey Spectrometer instrument
which divides the light from a fourth telescope between an imaging
detector and three EUV spectrometers.
The wavelength range is 10-60nm, corresponding to an energy range of
20-120eV, in the 4 bands:
10nm : Lexan/Boron, 58-174Å, 89Åpeak
DS: Lexan/Boron, 67-178Å, 91Åpeak (Deep Survey)
20nm : Al/Ti/C, 156-234Å, 171Åpeak
DS: Al/C, 157-364Å, 171Åpeak (Deep Survey)
40nm : Ti/Sb/Ti/Al, 368-590Å, 405Åpeak
60nm : Sn/SiO, 519-742Å, 555Åpeak
More details about the EUVE performances may be found in the paper by
Sirk et al. (1997ApJS..110..347S)
The EUVE Source Catalog published in 1996 paper is made of three
source tables, plus a list of associations for each table:
- survey.dat lists the 514 objects detected during the all-sky survey.
- deepsurv.dat lists the 35 sources detected by the deep survey of
half the ecliptic plane; three deep survey objects are also detected
in the all-sky survey.
- detect.dat lists 188 sources that have been detected in other ways,
principally by deep exposures with the scanner telescopes as part of
the Right Angle Program through 24 December 1994 (later RAP detections
are reported in the 1999 paper)
The corresponding association tables are idsurvey, iddeepsu.dat and
iddetect.dat respectively, in which one EUVE source may by associated
to 0, one or more counterparts. In nearly all cases the associated
objects lie within 1arcmin of the actual source position.
The all-sky catalog of faint EUV sources published in 1997 lists the
faint sources detected jointly by EUVE and ROSAT WFC.
The 1999 paper lists the detections made from the observations since
the first EUVE RAP catalog (1994 January) and covers 17% of the sky.

Note (1): the `Q' column indicates our level of confidence in each
source detection:
Q=1 denotes likely identification on basis of known EUV emitter from
previous work or from membership in a class of known EUV emitters.
Q=2 denotes acceptable positional coincidence but little or no
other supporting evidence.
Q=U denotes some of the detected source counts originate from the
known UV leak of one or more of the EUVE filters
Q=H means no counterpart has been found, but the detection is
statistically secure found, the detection is statistically
secure in the sense of its satisfying the more stringent
selection criteria.
Q= (a blank) indicates that the detection lies in the less stringent
group, and no other supporting evidence is available.

Note (1): Quality flag:
1: likely identification with supporting evidence as a previously
identified EUV source
2: although the detection is statistically significant, there was
no other supporting evidence
H: no identification was found
U: the source has a strong ultraviolet continuum, the reported
emission is outside the EUV bandpass, and is often referred to as
"ultraviolet leak" (McDonald et al., 1994AJ....108.1843M;
Vedder et al., 1993, Proc. SPIE, 1742, 486)
