Compiled catalog of the proper motions and infrared photometry of stars at the north Galactic pole
Tóm tắt
We describe the procedure we used to compile a catalog of the proper motions of 23 633 stars in the sky area covering about 700 square degrees at the north Galactic pole. The compiled catalog combines the data from the UCAC2, Tycho-2, and FONAC catalogs for stars down to V ∼ 14
m
in this sky area. In addition to proper motions, the catalog also contains the near-infrared magnitudes J, H, and K
s
in the 2MASS system. The mean accuracy is 2.5 mas/yr for proper motions and 0.03
m
for magnitudes.
