 coordinates and - if necessary - velocity information).
+Keywords are:
+  * SBAS: Basis system of the catalog - see below
+  * SNAM: source name
+  * SLAM: longitude of the source (in the coordinate system defined by SBAS)
+  * SBET: latitude of the source (in the coordinate system defined by SBAS)
+  * VLSR: velocity against the local standard of rest
+  * VHEL: velocity against the heliocentric movement
+  * VBAR: velocity against the barycentric movement
+The following basis systems are possible:
+^SBAS^System^
+|-1|equatorial coordinates, J2000.0|
+|0|galactic coordinates|
+|1|equatorial coordinates, B1950.0|
+|2|equatorial coordinates, equinox of date|
+Example catalog:
+<code>
+COMMON: SBAS= -1
+INDIVIDUAL: SNAM SLAM SBET VLSR
+! that's the header
+! SBAS = -1 -> coordinates are equatorial, J2000.0
+!
+! comments can be included with an exclamation mark
+! now comes the source part
+!
+SNAM=W3OH           ; SLAM=02 27 03.9   s; SBET= 61 52 24.0 "; VLSR=-44
+SNAM=ORION-S        ; SLAM=05 35 13.440 s; SBET=-05 24 08.10 "; VLSR=7
+! and so on, and so forth...
