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).
