Keywords: globular clusters: individual: NGC 4833 - HR diagram
Description:
A color-magnitude diagram for the galactic globular cluster NGC 4833,
based on the photographic BV photometry of about 868 stars in a
12'x12' field with an automatic measuring machine, is presented. It
reaches the cluster main sequence turn-off at V=~19.2mag; the difference
in V magnitudes between the turn-off and the horizontal branch
being normal.
