a) SDSS stamp for NGC 2916 (CALIFA 277). As in other images throughout this paper, the circles mark R = 1 and 2 Half Light Radius (HLR). b) CALIFA image in the rest-frame 5635 ± 45 Å interval after applying the spatial mask. c) Map of the S/N at 5635 Å. d) S/N map after the Voronoi binning. e) Number of spaxels in each Voronoi zone. Note that no spatial binning (N_z = 1) was necessary throughout the inner ~1 HLR. f) Percentage of bad pixels in the 3800−6850 Å range. North is up and east is towards the left in all images.
