In the first line of Col. 2, the source types are indicated with a letter code, as follows:
$\bullet$ A: atoll source (18);
$\bullet$ B: X-ray burst source (63);
$\bullet$ D: "dipping" low-mass X-ray binary (11);
$\bullet$ G: globular-cluster X-ray source (13);
$\bullet$ P: X-ray pulsar (5);
$\bullet$ T: transient X-ray source (76);
$\bullet$ U: ultra-soft X-ray spectrum. These sources include black-hole candidates; some "extreme ultra-soft'' (EUS) sources may be white dwarfs on whose surface steady nuclear burning takes place.
$\bullet$ Z: Z-type (7).
In the third line of Col. 2, we provide some information on the type of observation from which the source position has been derived. The following abbreviations have been used: o, optical; x, X-ray; r, radio; IR, infrared. A reference on the source position is given below the columnar information under "Pos.''. In addition, we give an indication of the accuracy of this position, in the form of equivalent (90 percent confidence level) error radii, but in several cases this can only be considered an approximation (e.g. when the error box is not circular). When no accuracy is quoted, it is about one arcsecond or better. Column 3 contains in the first two lines the right ascension (RA) and declination (DEC) of the source for epoch 1950 for the usual name, and for epoch 2000 for the sources with the names of J2000 coordinates. RA is given as hhmmss.s to an accurcy of 0.1 s, DEC is given in $^\circ~'~''$ , to an accuracy of 1''. The third line gives the galactic longitude and latitude to an accuracy of 0.1 $^\circ$ (except for sources close to the galactic center (GC), where these coordinates are given to 0.01 $^\circ$ ). The first and second lines of Col. 4 give names of an optical counterpart. The third line contains a reference to a finding chart. An asterisk followed by a number or letter refers to star numbers used in the finding chart; "star" refers to a star in the finding chart that has not been assigned a number or letter. Many optical counterparts have been indicated with a variable-star name, as given in the General Catalogue of Variable Stars and in recent name lists of variable stars as published regularly in the IAU Information Bulletin on Variable Stars, or a number in a well-known catalogue (e.g. HD, SAO). For X-ray sources in globular clusters, the cluster name is here given, in addition to the name of a stellar optical counterpart. The fifth column contains some photometric information on the optical counterpart. In the first line, the apparent visual magnitude, V, and the color indices B-V, and U-B, are listed. The second line contains the estimate of the interstellar reddening, E_B-V.
