The region is covered with a rich variety of multiband photometric and spectroscopic observations. Using the photometric data of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) and spectroscopic observation of the Baryon Oscillation Spectroscopic Survey (BOSS), we find that the galaxy has a stellar mass of $\\sim 10^{11.6}$ times of the solar mass $M_\\odot$. The galaxy has a red color and has an old stellar population, and thus its star formation has stopped.
