VizieR Online Data Catalog: ZTF Type II supernovae with follow-up obs. (Bruch+, 2021)
Abstract
The Zwicky Transient Facility (ZTF) is a wide-field, high cadence, multiband survey that started operating in 2018 March. ZTF imaging is obtained using the Samuel Oschin 48" Schmidt telescope at Palomar observatory (P48). ZTF observing time is divided into three programs: the public (MSIP) 3 day all-sky survey, partnership surveys, and Caltech programs. This paper is based on data obtained by the high-cadence partnership survey. As part of this program, during 2018, extragalactic survey fields were observed in both the ZTF g- and r-bands 2-3 times per night, per band. A 30s integration time was used in both g- and r-band exposures. We conducted our year-1 ZTF survey for infant SNe following the methodology of Gal-Yam+ (2011, J/ApJ/736/159). See Sections 2.1 and 2.2.
Our goal was to obtain rapid spectroscopy of real infant (RI) SN candidates. This was made possible using rapid ToO follow-up programs as well as on-request access to scheduled nights on various telescopes. The robotic Spectral Energy Distribution Machine (SEDm) at Palomar observatory was triggered for all candidates brighter than a threshold magnitude of 19mag in 2018. Higher-resolution spectra (using the 4.2m William Herschel Telescope (WHT), Gemini, or other available instruments) were triggered for events showing recent non-detection limits (within 2.5 days prior to first detection) as well as a significant rise in magnitude compared to a recent limit or within the observing night.
