J/A+A/14/164 UBV sequences in Cen (Mcgruder+, 1971) ================================================================================ Three UBV sequence in Centaurus. Mcgruder C.H., Schnur G. =1971A&A....14..164M ================================================================================ ADC_Keywords: Photometry, UBV ; Photometry, sequences Keywords: photoelectric photometry ; UBV magnitudes ; Centaurus Description: Photoelectric UBV observations were made with the ESO 1m telescope and the ESO photometer on 6 nights between 1970-04-01 and 1970-05-03. The observations were centered around (B1950)13:24-62:23 The positions and identifications of the 3 sequences were computed by B. Skiff (Lowell Obs.) in September 2010, from a comparison of the published charts with the computer screen-plots of UCAC2.
