S/N maps of GJ 758 showing J and H images separately for epoch 2013-07. The images are from first-pass S4 processing with ﹩{N}_{\mathrm{PC}}﹩ = 50–110, displaying somewhat weaker detection significance than the locally optimized spectral extraction presented in Table 3 and following figures. North and east orientation are up and left, respectively. The scale of 10 au at the distance of the star is represented by a white line to the lower left in each image, while the circle to the lower right shows the spatial resolution, FWHM = 0.″0958, measured from the PSFs of multiple core exposures. Both maps use the same linear color scale.
