Abstract :
This paper is an addendum to the time domain frequency stability test suite presented at the 1995 IEEE Frequency Control Symposium. It adds values for the new TOTALDEV statistic, and for the recently re-emphasized Hadamard deviation. Values are given for those quantities at several averaging factors for both the classic NBS data set and the 1000-point portable test suite. Plots are also presented that show the improved performance of the TOTALDEV statistic as compared with the normal Allan variance for averaging times that are a significant fraction of the record length. Also included is a correction to the value given in the original paper for the modified Allan deviation for the 1000-point test suite with an averaging factor of 100
