Beginning of ReadMe : J/A+AS/137/305 IC 348 proper motion catalogue (Scholz+, 1999) ================================================================================ IC 348 proper motion study from digitised Schmidt plates. Scholz R.-D., Brunzendorf J., Ivanov G., Kharchenko N., Lasker B., Meusinger H., Preibisch T., Schilbach E., Zinnecker H. <Astron. Astrophys. Suppl. Ser. 137, 305 (1999)> =1999A&AS..137..305S ================================================================================ ADC_Keywords: Clusters, open ; Photometry ; Proper motions Keywords: astrometry - methods: statistical - open clusters and associations: individual: IC 348 - stars: kinematics Description: A new proper motion study for about 1400 stars with R<18mag in a one square degree region around the young open cluster IC 348 based on Schmidt plates is presented. With an overall accuracy of about 3mas/yr (2.5mas/yr, respectively for all stars with R<17mag) we have obtained membership probabilities dividing our sample into three groups: foreground stars, cluster stars and background stars. This separation is also supported by the proper motion distribution with respect to the direction of the standard antapex and an increase of mean proper motion cluster membership probabilities with smaller cluster radii. 240 stars of our sample have cluster membership probabilities larger than 80%.
