We present interpretations of the line-of-sight velocity distribution of stars in the Draco dwarf spheroidal galaxy in terms of CDM and MOND assuming constant mass-to-light ratio and anisotropy .
We estimate the two parameters by fitting the line-of-sight velocity dispersion and kurtosis profiles for stellar samples differing by a number of stars rejected as interlopers .
The results of the fitting procedure for CDM , high mass-to-light ratio ( 131-141 solar units in V-band ) and weakly tangential orbits , are similar for different samples , but the quality of the fit is much worse when fewer interlopers are removed .
For MOND , the derived mass-to-light ratio ( 21 solar units ) is too large to be explained by the stellar content of the galaxy .
