5 Cosmological implications from CAT detections 

The mean broad-band power of the CMB fluctuations measured in the CAT1 and CAT2 fields, about , is broadly consistent with COBE-normalised CDM models (Scott et al. (1996); Hancock et al. (1997)). This value is lower than that measured by other experiments at scales, pointing to the existence of the first Doppler peak and constraining its position in -space (i.e. below ). This in turn places restrictions on cosmological parameters, showing and implying a low value of (Hancock & Rocha (1996), Hancock et al. (1997)). The existence of a peak at all also raises problems for defect models (see Turok, these proceedings).
