VizieR Online Data Catalog: Optical monitoring of the Seyfert I NGC 3516 (Noda+, 2016)

The X-ray monitoring observations of NGC 3516 were performed in the Suzaku AO-8 cycle during 2013-2014. Specifically, NGC 3516 was observed with Suzaku five times from 2013 April 10 to May 29, with intervals of ~1-2 weeks. Another pointing was carried out on November 7, and the last one on 2014 April 4, making a total of seven observations, with various intervals from days to months.

The optical photometric monitoring observations of NGC 3516 were performed by using the charge-coupled device (CCD) cameras installed at the Pirka, MITSuME, Kiso Schmidt, Nayuta, and Kanata telescopes. Simultaneous monitoring observations were performed at the same seven epochs as the X-ray observations by Suzaku. In addition, from 2013 January to 2014 April, these telescopes densely monitored the source even without simultaneous X-ray coverage, with a typical intervals of ~1 day. In the present paper, we present the B-band and g'-band photometric data, because the optical continuum emission of AGNs is generally bluer than that of the host galaxy, thus ensuring better sensitivity to the AGN signals.
