The plots show the difference TsysA-TsysB vs az and za for this dataset:run the correlator with 25 Mhz bandwidth, at 3200,3400,3600, and 3800 Mhz, sampling at 1 second intervals. drive the telescope in az at .2 deg/sec (half slew) from az 270 to 630. Do this at za=2,4.5,7,9.5, and 12 deg (reversing direction on each swing). Fire the cal 3 times during the measurements to convert to kelvins. For each az swing compute TsysPola- TsysPolB. For each az swing fit yfit(az)=c0 +c1*az + c2*cos(az)+c3*sin(az) + c4*cos(2az)+c5*sin(2az). Use the routine corblauto() for the fitting. This routine iterates the fit throwing out points greater than 3 sigma. The data was taken 11:45 to 14:20 hours so there is interference from the sun as well as continuum sources.
