The first argument to the adev1 program is the sampling interval t0. The program doesn't know how far apart the input file samples are taken so it is your job to specify this. The default is 1 second. If you have data taken one second apart then t0 = 1. If you have data taken two seconds apart then t0 = 2. If you have data taken 60 seconds apart then t0 = 60, etc. If, as in your case, you take raw one second data and remove every other sample (a perfectly valid thing to do), then t0 = 2. Make sense now? It's still "continuous data" in the sense that all measurements are a fixed interval apart. But in any ADEV calculation you have to specify the raw data interval. /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.
