reflector | adjustment dates |
primary | nov04 to jan05 |
secondary | 7jun04 to 29jun04 |
tertiary | 12octo4 to 30oct04 |
The primary and secondary had undergone a previous round of
adjustments.
The tertiary had not been looked at since it was on the ground
prior to
installation in the dome.
High frequency calibration data taken 01dec04 through 05feb05 was used to see how well the system was performing. Data from cb,cbh,xband was used. The plots show the system performance for the high frequency receivers: (.ps) (.pdf): The first 3 figures plot the gain, Tsys, SEFD, and FWHM beam width (in asecs) vs zenith angle for each receiver.
