Statistics, Graphs and Distributions. Data sample consists of 6984 triggers (3 sigmas above noise) from matched filter. 6-second kernel, first harmonic only. Fit using envelope-power-weighted centering iterated several times, and 5 fits, with ngate = 100, 300, 500, 1000, and 3000 points (+/-). A sixth fit (the "cheating fit") uses ngate = 3000, but with the starting values of the parameters set to the phi0 value calculated to start off with, and f0 = 16.00, dfdt = -0.045 Hz/sec.
