Locations of some recent field stellar population studies in the outskirts of M31, including fields (squares) targeted by the ground‐based studies of Morris et al. (1994), Reitzel, Guhathakurta, & Gould (1998), and Durrell, Harris, & Pritchet (2001), the WFPC2 studies (circles) of Holland, Fahlman, & Richter (1996), Rich et al. (1996), Sarajedini & Van Duyne (2001), Ferguson, Gallagher, & Wyse (2000), and Ferguson & Johnson (2001). Only the Morris et al. spur field and the Rich et al. G1 field lie close to halo substructures discovered in the present survey.
