VizieR Online Data Catalog: SDSS J1339+1310 spectra and light curves (Goicoechea+, 2016)
Abstract
We carried out long-slit spectroscopy of the lens system SDSS J1339+1310 (Inada et al., 2009AJ....137.4118I) in 2014 using the OSIRIS instrument on the 10.4m Gran Telescopio Canarias (GTC). We then extracted the optical spectra of the two quasar images (A and B) and the main lensing galaxy (G) on 27 March 2014 (R500R grism; Table 1) and 20 May 2014 (R500B grism; Table 2), i.e., at two epochs separated by approximately the time delay of the system. Previous GTC spectra (13 April 2013) were presented in Shalyapin et al. (2014A&A...568A.116S, Cat. J/A+A/586/A116). In addition, we conducted a monitoring campaign in 2009, 2012-2015 and early 2016 with the 2.0m Liverpool Telescope in the SDSS-r passband. This allowed us to construct an optical variability database of the two images of the gravitationally lensed quasar (Table 3). While Table 3 contains r-band magnitudes for 143 observation nights, an extended (updated) version is also available at the Glendama website (http://grupos.unican.es/glendama/q1339.htm)
