VizieR Online Data Catalog: Differential V-band phot. & RVs of V506 Oph (Torres+, 2019)
Abstract
V506 Oph was observed spectroscopically with two different instruments. Between 2010 May and 2017 February, we monitored the binary with the Center for Astrophysics Harvard & Smithsonian (CfA) Tillinghast Reflector Echelle Spectrograph (R~44000 covering the wavelength range 3900-9100Å) attached to the 1.5m Tillinghast reflector at the Fred L. Whipple Observatory on Mount Hopkins, Arizona; see Table 1. V506 Oph was also observed at the Fairborn Observatory in southeast Arizona near Washington Camp, between 2012 February and 2018 May. For this, we used the Tennessee State University 2m Astronomical Spectroscopic Telescope (AST) and a fiber-fed echelle spectrograph (wavelength range of 3800-8260Å and R=15000 at 6000Å); see Table 2.
Times of minimum light for V506 Oph have been recorded since 1928 by photographic, visual, and photoelectric/CCD techniques. We collect all 176 measurements that we are aware of (84 for the primary and 92 for the secondary) in Table 3. Differential photometry of V506 Oph in the V band was performed with the URSA WebScope at the University of Arkansas at Fayetteville and with the NFO WebScope near Silver City, New Mexico. V506 Oph (var) was measured along with two nearby comparison stars (comp; TYC 993-762-1, V=11.30, B-V=2.08, and TYC 993-0780-1, V=10.78, B-V=0.49). We obtained 8345 URSA images between 2003 July and 2012 June on a total of 129 nights and 7475 NFO images between 2005 January and 2013 June on a total of 234 nights; see Tables 5 and 6.
