Use TimeLab, Plotter, Stable32, or any other graphing application that supports Hadamard deviation. Any of these apps will also let you subtract the linear or quadratic trend from the data itself... but if all you want to do is view ADEV without the effects of drift, HDEV will do that. -- john _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
