 coordinates and - if necessary - velocity information). 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|
 +
 +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...
