VizieR Online Data Catalog: The SDSS Reverberation Mapping (SDSS-RM) project (Shen+, 2019)
Abstract
The SDSS-RM field is a single 7.2° field that coincides with the PS1 Medium Deep Field (MDF) MD07 (RAJ2000=213.704,DEJ2000=+53.083), which lies within the CFHT-LS W3 field. The SDSS-RM sample contains 849 broad-line quasars over a redshift range of 0.1<z<4.5. Most of the SDSS-RM quasars were previously spectroscopically confirmed quasars in SDSS-I-III.
The primary spectroscopy has been obtained with the SDSS telescope and the BOSS spectrographs. The first-season SDSS-RM spectroscopic data were taken from 2014 January to July in SDSS-III and consist of a total of 32 epochs with an average cadence of ~4days; each epoch had a typical exposure time of 2hr. The SDSS-RM program has continued in SDSS-IV, with ~12 epochs per year (2 per month) with a nominal exposure time of 1hr each during 2015-2017 and ~6 epochs per year (monthly cadence) during 2018-2020. As of 2018 July, we have obtained a total of 78 spectroscopic epochs and a spectroscopic baseline of 5yr (2014-2018). The wavelength coverage of BOSS spectroscopy is ~3650-10400Å, with a spectral resolution of R~2000. We obtained additional spectroscopic data with the Multiple Mirror Telescope (MMT)/Hectospec in 2017. Supporting photometric observations in both the g and i bands have been obtained primarily with the Steward Observatory Bok 2.3m telescope on Kitt Peak and the 3.6m Canada-France-Hawaii Telescope (CFHT) on Maunakea, which roughly cover the same monitoring period as SDSS-RM spectroscopy with a cadence of ~2 days in 2014 and reduced cadences in successive years (see Kinemuchi+, 2020, J/ApJS/250/10). In addition, we also have early multi-band photometric light curves from PS1 during 2010-2013 with a typical cadence of several days. The SDSS-RM field continues to be monitored with the PS1 system in five bands since 2016, albeit with reduced cadence (about weekly to monthly per band). (2 data files).- Publication:
