Half-light radius, R_e, and Sérsic index, n, in five HSC bands for 26 912 quiescent galaxies. These galaxies have morphological measurements in all five bands and R_e exceeds half of the seeing FWHM. The central panel shows the distributions of r-band in the R_e − n plane. Galaxies (points) are segregated into two classes of D_n4000: 1.5 < D_n4000 < 1.6 (dark blue) and D_n4000 > 1.6 (green). Black contours show the probability density of HectoMAP galaxies in the R_e − n plane derived from a Gaussian kernel estimator (KDE). The largest to the smallest contour enclose regions where the probability density exceeds the 10th to the 90th percentiles of the distribution. The upper and right panels show the marginal distributions in R_e and n, respectively, color-coded by the HSC band. The equivalently color-coded dashed lines indicate the medians of these distributions. To improve readability, the central panel displays a randomly selected 30% of the total sample. Histograms and isocurves are based on the total samples.
