Comparison of GDS/PCAL at Calibration Line Frequencies between X04 and C01

Attached plots are the comparison between X04 and C01 data where C01 is latest version of the calibration without the time varying parameters applied to it. X04 is the C01 data with time varying calibration parameters applied to it, except for the cavity pole. These  comparsions are made only at the calibration line frequencies and includes data from Sep 30- Oct 9. 

X04 agrees closely with PCAL both in phase and magnitude. The magnitude of C01 shows some discrepancy, especially at lower frequency, which can be attributed to the charging of testmass. There is 1 16-kHz cycle discrepancy in phase of C01 as well of which the calibration team is aware of and have plans to correct with the release of X04 (eventual C02).
