Statistics on the morphology of binary masks. The above results are based on all ∼127 thousand target stars within IF (see Sect. 3.3). (a) Cumulative count of unique binary mask shapes as a function of the cumulative count of target stars. (b) Cumulative count of unique binary mask shapes as a function of target P magnitude. (c) Average number of pixels composing the binary masks as a function of target P magnitude. (d) Cumulative number of pixels composing the binary masks as a function of target P magnitude.
