| Summary: | We account for experimental and observational uncertainties in likelihood analyses of cosmic microwave background anisotropy data from the MAX 4 and MAX 5 experiments. These analyses use CMB anisotropy spectra predicted in observationally-motivated open and spatially-flat A cold dark matter cosmogonies. Amongst the models considered, the combined MAX data set is most consistent with the CMB anisotropy shape in 0.1 -- 0.2 open models and less so with that in old 15 -- 16 Gyr, i.e., low h), high baryon density 0.0175 h-2), low density 0.2 -- 0.4), flat-A models. The MAX data alone do not rule out any of the models we consider at the level. Model normalizations deduced from the combined MAX data are consistent with those drawn from the UCSB South Pole 1994 data, except for the flat bandpower model where MAX favours a higher normalization. The combined MAX data normalization for open models with 0.1 -- 0.2 is higher than the upper value of the DMR normalization. The combined MAX data norma. |
