Using White Dish CMB Anisotropy Data to Probe Open and Flat-A CDM Cosmogonies
We usedata from the White Dish experiment to set limits on cosmic microwave background radiation anisotropies in open and spatially-flat-A cold dark matter cosmogonies. We account for the White Dish calibration uncertainty, and over the offset and gradient removed from the data. Our 2-u upper limits...

Summary: | We usedata from the White Dish experiment to set limits on cosmic microwave background radiation anisotropies in open and spatially-flat-A cold dark matter cosmogonies. We account for the White Dish calibration uncertainty, and over the offset and gradient removed from the data. Our 2-u upper limits are larger than those derived previously. These upper limits are consistent with those derived from the data for models tested. Subject headings: cosmic microwave background- cosmology: observations---large-scale structure of the universe -31. Introduction Ganga et al. (1997a, hereafter developed techniques to account for uncertainties, such as those in the beamwidth and calibration, in likelihood analyses of cosmic microwave background anisotropy data. GRGS and Ganga et used these techniques, in conjunction with theoretical CMB anisotropy spectra, in analyses of the UCSB South Pole 1994 et al. 1995), the (Church et al. 1997), and the MAX 4+5 (Tanaka et al. 1996; Lim et al. 1996, and ref. |
