Data pubblicazione: | 2015 | Rivista: | VizieR Online Data Catalog | Numero: | 150 | Fascicolo: | 4 | Da pagina:: | I/331 | Abstract: | The APOP is a absolute proper motion catalog achieved on the Digitized Sky Survey Schmidt plates data established by GSC-II project that outside the galactic plane (|b|>27°). The sky cover of this catalog is 22,525 square degree, the mean density is 4473 objects/sq.deg. and the magnitude limit is around R=20.8mag. The systematic errors of absolute proper motions related to the position, magnitude and color are practically all removed by using the extragalactic objects. The zero point error of absolute proper motions is less than 0.6mas/yr, and the accuracy is better than 4.0mas/yr for objects bright than R=18.5, and rises to 9.0mas/yr for objects with magnitude 18.5<R<20.0. <P />We believe the catalog is reliable for operational applications and will be also fine for astrophysical research. But the user should use this catalog with that in mind, the accuracy condition is good for objects with Declination>-30 degree and is not very well for others, the reason is that the epoch difference is large for Declination>-30° (45 years) but South than that is only around 12 years. It is fine for statistical studies for objects with Declination<-30° that people could find and remove obviously incorrect entries.
