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.
