VizieR Online Data Catalog: 43yr spectrosc. monitoring of the Pleiades region (Torres+, 2021)
Abstract
Spectroscopic monitoring of the Pleiades region at the Center for Astrophysics (CfA) began in December of 1981, and was carried out with four instrument/telescope combinations. From that initial date until February of 2009, spectra were gathered with three nearly identical copies of the Digital Speedometer. They were attached to the 1.5m Tillinghast reflector at the Fred L. Whipple Observatory on Mount Hopkins (AZ), the now-closed 1.5m Wyeth reflector at the Oak Ridge Observatory (MA), and the 4.5m equivalent MMT also on Mount Hopkins, before its conversion to a monolithic 6.5m telescope. The Digital Speedometers had a resolving power of R~35000.
Beginning in October of 2009, further observations were collected with the Tillinghast Reflector Echelle Spectrograph (TRES) on the 1.5m Tillinghast reflector. This is a modern, bench-mounted, fiber-fed spectrograph delivering a resolving power of R~44000, with a CCD detector that records 51 echelle orders between 3800-9100Å. We gathered 3663 spectra with this instrument through the end of the 2020/2021 observing season. (9 data files).- Publication:
