Scientific paper

We analyze whether the large variance of the temperature field measured by the Tenerife experiment can be obtained by sampling an active region of a cosmic microwave sky characterized by a matter power spectrum with slope n = 1. We employ the technique of constrained realizations of Gaussian random fields to generate sky maps, smoothed to COBE Differential Microwave Radiometer scales, containing a hot spot at a prespecified location. We show that when Tenerife is normalized to Qrms-PS = 20 μK, the high variance can be explained at the 68% confidence level as originating from a 2.5 σ or larger deviation from a scale-invariant power spectrum.
