Historic light curves of 3 known blazars
Listed in IVOA Registry (Virtual Observatory)
We present the historic photographic light curves of three little known blazars (two BL Lac objects and one FSRQ), GB6 J1058+5628, GB6 J1148+5254, and GB6 J1209+4119, spanning a time interval of about 50 years, mostly built using the Asiago plate archive.
Description
All objects show evident long-term variability, over which short-term variations are superposed. One source, GB6 J1058+5628, showed a marked quasi-periodic variability of 1mag on timescale of about 6.3 years, making it one of the few BL Lac objects with a quasi-periodic behavior.
