Maybe I should read up on obsfucation of C. Can't have you read this code... ;) Cheers, Magnus

Thanks very much, Magnus -- this code will come in handy. I should be able to get an incremental version into the next TI.CPP beta. -- john

Most of these allow for incremental versions, so it should not be too hard. Do use the test-sequence and check against the listed values so that you know that the algorithm does what you think it does. Verify your implementations! I've implemented the Theo-variants, MTIE and TIErms also. But I have not verified them as there is no correct values. In the process I'e discovered an error in SP1065 relating to Time Total Variance (and thus Deviation). The factor of tau^3/3 should be tau^2/3. The author was unaware of it, confirmed it and forwarded the info such that next printing can be correct. Cheers, Magnus

Hi John Miles,   Is there an instruction manual available for LadyHeather to interpret the displayed values like PPS, and other values. Thank You for making such valuable software available to everyone.  Best regards, Sal C.

No; so far, everyone (including myself) has had to rely on Mark's generous and informative tech support. :) -- john > -----Original Message----- > From: time-nuts-bounces@febo.com [mailto:time-nuts-bounces@febo.com]On > Behalf Of SAL CORNACCHIA > Sent: Thursday, January 21, 2010 7:41 AM > To: Discussion of precise time and frequency measurement > Subject: Re: [time-nuts] Modified Total Deviation calculation > > > Hi John Miles, >   > Is there an instruction manual available for LadyHeather to > interpret the displayed values like PPS, and other values. > Thank You for making such valuable software available to everyone. >  Best regards, > > Sal C.
