Beginning of ReadMe : J/AJ/134/1432 Proper motions in Plaut's window (Vieira+, 2007) ================================================================================ Proper motions in the Galactic Bulge: Plaut's window. Vieira K., Casetti-dinescu D.I., Mendez R.A., Rich R.M., Girard T.M., Korchagin V.I., Van Altena W., Majewski S.R., Van Den Bergh S. <Astron. J., 134, 1432-1446 (2007)> =2007AJ....134.1432V ================================================================================ ADC_Keywords: Stars, nearby ; Proper motions ; Photometry, infrared Keywords: astrometry - catalogs - Galaxy: bulge - Galaxy: disk - stars: kinematics Abstract: A proper-motion study of a field of 20'x20' inside Plaut's low-extinction window (l,b) = (0deg, -8deg) has been completed. Relative proper motions and photographic BV photometry have been derived for  21000 stars reaching to V 20.5mag, based on the astrometric reduction of 43 photographic plates, spanning over 21yr of epoch difference. Proper-motion errors are typically 1mas/yr, and field-dependent systematics are below 0.2mas/yr. Cross-referencing with the 2MASS catalog yielded a sample of  8700 stars, from which predominantly disk and bulge subsamples were selected photometrically from the JH color-magnitude diagram. The two samples exhibited different proper-motion distributions, with the disk displaying the expected reflex solar motion as a function of magnitude. Description: This investigation is based on 43 photographic plates, taken with five different telescopes: the 51cm Double Astrograph at the Yale Southern Observatory (YSO) in El Leoncito, Argentina; the 2.1m at KPNO; the du Pont 2.5m at Las Campanas; the Blanco 4m at CTIO; and the Hale 5m at Palomar Observatory.
