Cold Molecular Material in the Galaxyally measured by observing the CO J = 1 → 0 transition and assuming that this line is optically thick and thermalized. This assumption also underlies estimates of the total mass and distribution of molecular material in our galaxy based on CO surveys. Because a significant amount of molecular materi

M82 — Tilt and Warp of its Principal Planeon of its principal plane is complicated by its very irregular appearance and the presence of scattered light. We have used three-colour UBVphotometry of this galaxy to determine the stellar population, using the extinction- free parameter Q = (U-B) - 0.65(B-V), and the extinction A.=4 ((B-V)-(B-V).

HI Observations of the Irregular Galaxy IC 10De Vaucouleurs and Freeman (1972) have classified it as a Magellanic barred irregular. With a heliocentric radial velocity of -350 km/sec, its distance is uncertain, and various investigators have placed it as far away as 3, and as near as 1 Mpc (Bottinelli et al., 1972; Roberts, 1962). For the latter value, IC 10 would be a Local Group member.
