Description:
These tables give the mean radial velocities for 591 stars in the
vicinity of the globular cluster M15 (NGC 7078). 230 of these are
members of the cluster, the remaining 361 are most likely
non-members, although the membership, or otherwise, of the faintest
stars with velocities near that of the cluster was impossible to
determine. The radial velocities were measured using the Hydra
multi-object spectrograph on the WIYN telescope. For cluster
members, the median uncertainty is 0.3 km/s.

Nomenclature Notes:
Stars with names starting with K are from Kustner (1921VeUSB..15....1K 1921VeUSB..15....1K)
Those with AC are from Auriere & Cordoni (1981A&AS...46..347A 1981A&AS...46..347A).
The others with single alphabetical prefixes are from Sandage
(1970ApJ...162..841S 1970ApJ...162..841S). Those with Geb are from Gebhardt
(1997AJ....113.1026G 1997AJ....113.1026G). The numerical identifications are our own.

Note (1):
Probability that velocities of stars with multiple observations are
consistent with no variability. This is blank for stars with only a
single observation.
Note (2):
b: Star remains variable if jitter of 0.8 km/s is included.
j: Star is not variable if jitter of 0.8 km/s is included.
v: Variable star fainter than jitter limit.
