POLARIZATION - Lband - GBT - Oct 2007
Good behavior, XX and YY [10/7/07]
Simultaneous good XX, bad YY [10/7/07]
Simultaneous good XX, band YY waterfall [10/7/07]
Sample Spectra from Scan 26 [10/8/07]
Calibration Attempt [10/9/07]
Power Drop [10/10/07]
Power Drift [10/10/07]
Calibrator Scans [10/12/07]
Plots for Abell 576
Plots for Abell 907
Plots for Coma
Good behavior, both XX and YY, 5 repeated scans (A576, RA stripe 19, 10/7/07)- integrated over spectrum
Simultaneous good (OK) XX, bad YY, stripe , 10/7/2007, integrated over spectrum
Waterfall plots (vertical:time; horiz: freq ch), XX then YY, scan 26 and IF 0 (ignore freqency axis labels, they are wrong for these two plots);
10/7/07
Sample spectra from scan 26; 10/8/07
First attempt to calibrate the gain and phase as a function of frequency. The spectra shown are for one
integration (the first) for RAstripe3 on Coma. I used a combination of an on-off scan of 3C48 and the cal scan
for this stripe to correct the original spectra (top) for the gain and phase (shown below). There is still
something wrong with the cross-correlations, which should flatten out if I got the phase correct...?
Scans across Abell 907 when the power level dropped in YY but not in XX.
Scans across Abell 907 when you can see the power level drifting from scan to scan.
Scans across calibrator sources 3C286 and 3C48.
