... The first column gives the star identification number, followed by X, Y positions in mm. The zero point of these offsets is star number 1 which lies at 21:24:20.52 +36:30:25.6 (equator and equinox 2000). Next are relative proper motions (muX and muY) and their errors (ex and ey) in 10**4 arcsec/yr, followed by calculated V magnitudes. The final column gives the calculated membership probabilities in percent. ...
