Only Stable32 handles data gaps seamlessly. Give it a try (read the manual for details).
But also ask yourself how much gaps matter. Yes, they affect the accuracy of your y-axis sigma scale and your x-axis tau scale. A few seconds every 30 minutes is, what, a 0.1% error? That's like one pixel in a ADEV plot; not significant. What I've done when I need a perfectly seamless data set is just interpolate for rare and obviously missing phase data points. That keeps the timescale intact. This is especially important if you plan to Fourier transform the data: under no circumstances do you want to slip a sample in that case. /tvb ----- Original Message ----- From: "jimlux" <[email protected]> To: "Discussion of precise time and frequency measurement" <[email protected]> Sent: Thursday, May 25, 2017 6:11 AM Subject: [time-nuts] calculating stats with gaps in the data > I'm looking at the python AllanTools package.. does it deal with gaps in > the data series (e.g. I've got a series of phase and/or frequency > measurements, 1 per second, but there's gaps of a few seconds every 30 > minutes or so) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
