Show affiliationsThis note rectifies oversights and errors in the author's recent paper about a clock ensemble algorithm based on a modified Kalman filter. It is shown by simulation and theory that initial frequency state errors can cause the corrected clocks to diverge linearly with time. Two statements about the Brown ensemble algorithm are corrected, and results of that algorithm are compared with those of the author's algorithm for a simulated three-clock ensemble.
