Caption: Figure 4.

Left: The stellar-mass functions over the entire sky, after ZoA correction and galaxy cloning, for luminosity-distance ranges labeled in the figure. The stellar-mass function estimated in Wright et al. (2017) is shown for reference as a gray dashed line. Colored lines show the scaled mass functions accounting for the 2MPZ sensitivity limit. Right: The fraction of observable stellar mass as a function of luminosity distance above the sensitivity threshold of 2MRS (solid gray line), 2MPZ (solid black line), and WISE × SCOS (dashed black line). The 400 Mpc cut placed by the MANGROVE authors is indicated as a vertical solid line. The black points display the observed stellar-mass density, Ω*,2MPZ, in 25 Mpc thick layers beyond the Virgo cluster (>25 Mpc), normalized to a reference value, Ω*,ref., from the GAMA/G10-COSMOS/3D-HST survey of galaxies at z ∈ [0.02, 0.08] (Driver et al. 2018). Points beyond 400 Mpc correspond to galaxies with a photometric distance in the MANGROVE sample superseded by a spectroscopic estimate in the present work. The uncertainties on the density ratios are dominated by correlated uncertainties on Ω*,ref. (thin gray lines) rather than by uncorrelated uncertainties on galaxy counts (thick gray lines within markers).
