The stars of dwarf galaxy And XXIX observed with GMOS on a color-magnitude diagram

The solid points show the stars of dwarf galaxy And XXIX observed with GMOS on a color-magnitude diagram; open diamonds were measured from SDSS observations. The near-vertical lines show the predicted location of the red giant branch stars, for two different assumptions about metal abundance. The horizontal line marks the magnitude of the tip of the red giant branch, which implies a distance to And XXIX of about 730 kiloparsecs (nearly 2.4 million light years).
