The main purpose of the series of tests conducted at CESR in September was to verify the co-alignment of the five radiometer beams, and to adjust OSIRIS such that it also looks in the same direction as the radiometer. Note that results for OSIRIS are documented separately by Nick Lloyd and Doug Degenstein in "OSIRIS Beam Alignment Results from Toulouse September 2000". The measurements were not done in an anechoic environment, so we do not have accurate beam profiles of the radiometer down to the sidelobe levels,however, the main lobe is well measured. Another goal of the campaign was to measure the difference that is made in the beam profile when the telescope is heated up to a uniform temperature across the main reflector. The five channels of the radiometer are all very well co-aligned. OSIRIS is co-aligned with the beam direction of the radiometer. Heating the telescope did not produce any measurable difference, within the accuracy of the measurement setup.
