SDSS J1339+1310 spectra and light curves

We spectroscopically re-observed the gravitational lens system SDSS J1339+1310 using OSIRIS on the GTC. We also monitored the r-band variability of the two quasar images (A and...我们使用搭载于加那利大型望远镜（GTC）的OSIRIS光谱学重新观测了引力透镜系统SDSS J1339+1310。我们还对两颗类星体图像（A及……）的r波段光变进行了监测。
