VizieR Online Data Catalog: SEAMBHs. XI. Mrk 142 X-ray to optical light curves (Cackett+, 2020)

A large, coordinated monitoring campaign on Mrk 142 took place from 2018 October-2019 June. The core of the campaign was centered around X-ray and UV/optical observations taken with Swift. In addition, we obtained further X-ray observations with NICER, as well as supporting ground-based photometric and spectroscopic monitoring from multiple telescope sites.

Here, we focus only on the Swift and ground-based photometric data. The ground-based monitoring involved the Las Cumbres Observatory (LCO), the Liverpool Telescope, the Dan Zowada Memorial Observatory, and the Yunnan Astronomical Observatory.

Mrk 142 was monitored by Swift from 2019 January 1 to 2019 April 30 through Cycle 14 proposal 1417139 (PI: E. M. Cackett). In total, 185 epochs of observations were obtained. See Section 2.1. LCO is a global network of robotic telescopes.

As part of an LCO Key Project (KEY-2018B-001, PI: R. Edelson), monitoring was obtained in Sloan u, g, r, i, and PanSTARRS z filters from both the 2m Faulkes Telescope North at the Haleakala Observatory (OGG), and the 1m telescope at the McDonald Observatory (ELP). Observations with LCO took place between 2018 December 15 and 2019 June 19. See Section 2.2.

Photometric monitoring was obtained with the robotic 2m Liverpool Telescope (LT) located on La Palma, Spain through program PL19A01 (PI: M. Goad). Observations were taken using the IO:O instrument in u, g, r, i, and z filters and took place between 2019 January 3 and 2019 April 22.

The Zowada Observatory is a robotic 20 inch f/6.8 PlaneWave telescope located near Rodeo, New Mexico, and is owned and operated by Wayne State University. Observations began on 2018 October 31 and continued daily (when possible) until 2019 May 30. Images were obtained using u, g, r, i, and z filters.

Observations at the Lijiang Station of the Yunnan Observatories, Chinese Academy of Sciences, were obtained with the 2.4m telescope. The telescope is equipped with the Yunnan Faint Object Spectrograph and Camera (YFOSC), which is a versatile instrument usable both for photometry and spectroscopy. While the Lijiang telescope was primarily used for spectroscopy, images in the V filter were also obtained as part of the program. Observations span from 2018 October 22 to 2019 June 21.
