Detailed Description of J/A+AS/143/391 : ROSAT HRI catalogue of LMC X-ray sources (Sasaki+, 2000)
|
 |
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.

Description:
The ROSAT HRI LMC source catalogue is based on all 543 pointed
observations of the ROSAT HRI between 1990 and 1998 with exposure
times higher than 50 sec. The observations covered a 10 deg x 10 deg
field including the LMC. The catalogue contains 397 X-ray sources.
Sources showing flux variability in ROSAT HRI and PSPC are listed in
Table 1. Table 2 contains HRI sources which were identified with known
objects in other catalogues and literature. Table 3 is a list of new
classifications. The whole source catalogue from HRI observations is
given in Table 4.

Note (1): For sources which are listed in the ROSAT PSPC catalogue
(Haberl & Pietsch, 1999, Cat. J/A+AS/139/277) PSPC count rates are
taken from the catalogue. Otherwise PSPC count rate is the 2 sigma
upper limit from maximum likelihood algorithm ('<' in column Uplim).
Note (2): fg: foreground
Candidates from literature are marked with '?' behind the source class
