By marginalizing over solutions to the spherical Jeans equation, mass profiles for five of the Andromeda satellites were found. From the kinematics of And I, II, III, X, and XIV, the average mass contained within 300 parsecs is shown to be ~2 times smaller than the analyzed Milky Way dwarf spheroidals. In addition, And II is shown to be rotating--an effect that warrants further investigation to more accurately model its mass.
