Homogenous data for all the Messier objects of their various types are plainly unavailable from professional sources, so our compilation is necessarily preliminary and far from being perfect, even if we completely disregard the generally poor availability of acurate distances. An amateur attempt was undertaken by Don Machholz, who determined apparent visual brightness (in magnitudes) and apparent diameters (in arc minutes) in his booklet, Messier Marathon Observer's Guide; look at his list.
