Image Details
Caption: Fig. 2.
(a) Summed image of the 12 R‐band exposures of CTQ 414 taken at LCO. The scale for the image is 0﹩\farcs ﹩2278 pixel−1. East is at the top and north is to the left. The fainter component is at P.A. 251° east of north. (b) Summed image after fitting and subtracting two stellar PSFs from the individual frames. (c) Summed image after fitting and subtracting two stellar PSFs plus a pseudo‐Gaussian from the individual frames. (d) Summed image after fitting and subtracting two stellar PSFs from the individual frames, but leaving the pseudo‐Gaussian unsubtracted. Contrast in (b) and (c) is higher by a factor of 12 than in (a). Contrast in (d) is higher by a factor of 4 than in (a).
