VizieR Online Data Catalog: SDSS J1339+1310 light curves and spectra (Shalyapin+, 2021)

We present new light curves and spectra of the lens system SDSS J1339+1310 (Inada et al., 2009AJ....137.4118I). Table 1 contains updated brightness records of the two images of the gravitationally lensed quasar (A and B) covering the period from 2009 to 2019. Although most photometric data are based on observations with the 2.0m Liverpool Telescope and Sloan r filters (in 213 out of 241 epochs), the optical variability database also relies on red imaging from the Panoramic Survey Telescope and Rapid Response System project (Flewelling et al., 2020ApJS..251....7F), the 1.5m Maidanak Telescope and the 1.3m SMARTS Telescope. In addition, SDSS J1339+1310 was spectroscopically observed with the 2.4m Hubble Space Telescope on 18 February 2016 (Lusso et al., 2018ApJ...860...41L, Cat. J/ApJ/860/41). These observations were made using the G280 grism in the UVIS channel of the WFC3 instrument, and we extracted the UV-visible spectra of A (Table 3a) and B (Table 3b) at such observing epoch. Observations with the XSHOOTER spectrograph on the 8.2m Very Large Telescope on 6 April 2017 (programme 099.A-0018, PI: M. Fumagalli) were also used to extract the UV-visible-NIR spectra of both quasar images and the main lensing galaxy G (Table 4).
