[time-nuts] Is my Cs C-Field set OK or do I need to take more data?

Hi:

My plot of the FTS4060/S24 has now been going for 256,260 seconds (almost 3 days).  Between 124,920 and 169,680 seconds (12.4 hours) the 1 PPS input to the PRS10 was removed and when reconnected caused a negative swing that lasted until 248,400 seconds.  But it appears that a C-Field setting of 913 is pretty close to correct.  The drift is in the E-13 ot E-14 area.  The plot is at:

Having a Cs source allows seeing how the Rb source is working without the Cs source it was very difficult to impossible to seperate the Rb performance from GPS performance.

Have Fun,
