P., Roshchina E. A., Izmailov I. S. data included in standard data file: no Comments. Many observations made in 2007-2011 are the result of reprocession of observations contained in um0085.txt, um0086.txt, um0102.txt, and um0103.txt. The data were reprocessed by using the UCAC4 catalogue. Format. 1. Number of satellite (N): 1 - U1, 2 - U2, 3 - U3, 4 - U4 2. Julian date of the moment of observation 2.
