Descripción
Johnson B CCD photometry of quasars and other active nuclei were obtained with the 1-m and 2.5-m reflectors of the Roque de los Muchachos Observatory in the Canary Islands between 1986 and 1987. Data are presented for PKS 1538+149, 3C 345, 3C 351, and BL Lac. Error sources are discussed, and it is noted that at least part of the error is due to uncertainties in the magnitudes of the observed sequence stars.
