Extended Data Fig. 2: The effect of adopting different thresholds to delineate disks, intermediates and ellipticals in Sibelius.

From: Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a ΛCDM prediction

Extended Data Fig. 2

Analogous to Fig. 2, each panel shows the excess of ellipticals and disks at ∣sin(SGB) ∣ < 0.2, for different delineations between disks and ellipticals in Sibelius, as parameterized by bulge-to-disk ratios, less than 1/A for disks and greater than A for ellipticals. The top row shows, from left to right, A = 3 and A = 4, while the bottom row shows A = 5 and A = 6. For reference, the 2MRS data is repeated on each panel. The greater abundance of ellipticals compared to disks at low supergalactic latitudes in Sibelius, and its dependence of N, is not sensitive to the particular choice of A.
