References: 1: The observations were made in the Cousins R filter. Standard procedure of image reduction included dark removal and flatfield correction. 2: The observations were reduced using the same procedure as the observations from the 1.54-m La Silla, see Pravec et al. (2014) for details. 3: The observations were carried with a 1-m Ritchey-Chrétien telescope at Simeiz Department of the Crimean Astrophysical Observatory using camera FLI PL09000. The observations were made in the Johnson-Cousins photometric system. Standard procedure of image reduction included dark removal and flatfield correction. The aperture photometry was done with the AstPhot package described in Mottola et al. (1995). The differential lightcurves were calculated with respect to an ensemble of comparison stars by the method described in Erikson et al. (2000) and Krugly (2004). 4: The Shed of Science South utilizes a 0.5m Corrected Dall Kirkham telescope operating at a focal ratio of f4.5 and a pixel
