Description:
A catalogue of proper motions and photographic B,V magnitudes for stars up to
B=19 mag within a region centered near Alcyone is presented. The catalogue is
based on MAMA measurements of 8 plates taken with the Tautenburg Schmidt
telescope. The survey includes ca. 14500 stars and covers a total field of
about 9 square degrees. Membership probabilities, proper motions and B,V
magnitudes are listed for 442 stars up to B=19 mag in the Pleiades field.

Note (1): When '*' the stars have a membership probability based on their
proper motion (ppm) larger than 50% and they match photometric
criteria; when 'x' they have a ppm larger than 50% but they don't
match photometric criteria; when '+' their ppm is smaller than 50%
but they match photometric criteria; when there is an empty space
their ppm is smaller than 50% and they don't match photometric
criteria.
