We discuss variants of Cold Dark Matter (CDM) that give good agreement with a range of observations. We consider models with hot dark matter, tilt, Ω < 1, or a cosmological constant. We also discuss the sensitivity of the results to other parameters, such as the Hubble parameter and the baryon fraction. We obtain constraints by combining the COBE data… (More)
