The recent data from the Boomerang and MAXIMA-1 balloon flights have marked the beginning of the precision era of Cosmic Microwave Background anisotropy (CMB) measurements. We discuss the observational constraints from the current CMB anisotropy measurements on the simplest inflation models, characterized by a single scalar field φ, in the parameter space consisting of scalar spectral index and tensor/scalar ratio r. The data are consistent with the simplest assumption of a scale invariant power spectrum, but the specific error contours in the plane depend on prior assumptions, particularly the baryon density of the universe and the reionization history. Models with significant “red” tilt and appreciable tensor fluctuations are disfavored in all cases.
