Correct. That code, like most ADEV calculations, assumes you have phase data, and so it uses the "x" form of the formula. If the data is period or frequency then you use the "y" form of the formula. See: http://www.wriley.com/paper2ht.htm for details on both equations. See also: http://leapsecond.com/tools/adev_lib.c which computes ADEV, MDEV, and HDEV from phase. /tvb _______________________________________________ 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.
