The radial velocity given in this column is 
that as given by the authority mentioned in 
the next column. If the star has been observed 
at more than one observatory, the mean 
radial velocity has been taken, without any 
difference in weight. To the Bonn radial veloeities 
the correction as given in A. N. 198 No. 22 
has been applied. Often the older observations 
have been omitted if modern ones were 
available. 
For the spectroscopical binaries, the velocity 
of the system has been given according to the 
last known orbit-determination. 
The biggest radial velocities mentioned in this 
catalogue for the different types are, for 
B stars + 102 KM. sec. and — 38 KM. see
