Beginning of ReadMe : J/AJ/98/1693 UBVRI photometry of NLTT stars (Ryan 1989) ================================================================================ Subdwarf studies. I. UBVRI photometry of NLTT stars. Ryan S.G. <Astron. J. 98, 1693 (1989)> =1989AJ.....98.1693R ================================================================================ ADC_Keywords: Photometry, UBVRI ; Stars, subdwarf ; Stars, high-velocity Description: UBVRI photometry is presented for a sample of 1656 southern stars, including 1211, that were previously not measured, drawn from the NLTT (Luyten, 1979; catalogue I/98) proper-motion catalog; the catalog is shown to be a rich source of subdwarfs. The normalized UV excess, d(U-B)0.6, photometric parallax, and interstellar reddening are calculated for each star when possible. Residuals between the photometry and the magnitudes published in the NLTT catalog indicate that the latter have a large scatter ( 0.6mag) and therefore the values tabulated in the NLTT catalog must be regarded as approximate only. The erratum (Astron. J. 99, 1336) which deals with position angles of proper motions (pmPA) has been taken into account.
