Description
The complete set of data from the Tenerife 10-GHz (8-deg FWHM)
twin-horn, drift scan experiment is described. These data are affected
by both long-term atmospheric baseline drifts and short-term noise. A
new maximum entropy procedure, utilizing the time invariance and spatial
continuity of the astronomical signal, is used to achieve a clean
separation of these effects from the astronomical signal and to
deconvolve the effects of the beam-switching. We use a fully
positive/negative algorithm to produce two-dimensional maps of the
intrinsic sky fluctuations. Known discrete sources and Galactic features
are identified in the deconvolved map. The data from the 10-GHz
experiment, after baseline subtraction with the MEM, are then analyzed
using conventional techniques, and new constraints on Galactic emission
are made.
