Positions, magnitudes, and colors for stars in the globular cluster M92.
Abstract
B, V magnitudes and relative positions for all the stars brighter than B = 18. and V = 17.5 in an annulus ranging from r = 1.5 arcmin to r = 4.5 arcmin from the centre of the cluster NGC 6341 = M92 have been using a reduction procedure applied to digitized photographic data. Moreover, B, V magnitudes (and positions) for a second sample of stars are given in order to allow a better definition of the main branches in the Color Magnitude Diagram The accuracy of the data is discussed in detail.
