Grey scale showing for AVOCADO dwarfs of each ASK class the normalised distribution of (projected) distances to the closest luminous () galaxy in the 2MRS catalogue. The three vertical lines indicate, in each case, the 2.5, 50 and 97.5 per cent quantiles of the R_P distributions, and the corresponding ASK template spectra are shown, in logarithmic flux scale, for reference. ASK classes are sorted, from top to bottom, in order of decreasing current star formation activity. We find a strong environmental trend for the non-star-forming ASK 3 galaxies, which are only found closer than ≈ 1.5  Mpc from a luminous companion – i.e., isolated quiescent dwarfs are essentially absent in the  Mpc volume we probe.
