Description:
Heliocentric radial velocities accurate to ≲50km/s are given for
1267 galaxies in the fields of 14 rich clusters from the Dressler
(1980, Cat. VII/174) catalog (instead of 1268 velocities in 15
clusters as indicated in the title).

--------------------------------------------------------------------------------
Note (1): Velocity determination:
e: velocity determined from emission lines
b: both emission lines and cross correlation with a K giant spectrum
were equally weighted to determine cz.
The remaining cases are those determined solely by cross correlation
