J/AJ/109/1055 Globulars of M81 (Perelmuter+ 1995)
================================================================================
The Globular Cluster System of M81
Perelmuter J.M., Racine M.
<Astron. J. 109, 1055 (1995)>
=1995AJ....109.1055P
================================================================================
ADC_Keywords: Clusters, globular; Photometry
Description:
Photometric BVR, morphological, and astrometric information has been
obtained on 3774 objects located within a 25' radius of M81. This
catalogue is complete for 15 <= V <= 21. Small but
significant systematic errors in Madore et al.'s [AJ, 106, 2243
(1993)] photometry could be responsible for an overestimate of the
Cepheid distance to M81 [(m-M)0 = 27.8].

The level of significance of the total proper motion, mu/sig_mu,
where mu is the total proper motion = (pmGlon^2 + pmGlat^2)^(1/2)
