THE TENERIFE OBSERVATIONS .3. CMB FEATURES IN THE DATA AND A COMPARISON WITH COBE

The nature and stability of statistically significant structure in the Tenerife data is investigated. Analysis of independent subsets of the data confirms the consistency of the experiments and supports the pre sence of structure at an amplitude in agreement with the likelihood an alysis of the complete data set. The cross-correlation of the data fro m the 15 GHz and 33 GHz instruments demonstrates a common origin for t he structure detected at these frequencies. A Galactic origin is incom patible with the observations, which are fully consistent with a CMB s pectrum, leading us to assign a cosmological origin to the well-define d features present. The statistical properties of the features are in agreement with the published COBE DMR results (Smoot et al., 1992), al though a slightly higher value of n = 1.7 is favoured for the power sp ectrum slope.
