Indeed. TA(k) are independent time scales, apparently not steered in either phase or frequency. They in fact run at a variety of frequencies relative to TAI; it looks as though several, but not all, have the frequency of proper time at the laboratory's altitude. The recommendation that Michael Deckers referred to does not say otherwise. It defines "TA(k)" quite distinctly from "TAI(k)", such that TAI(k) is a realisation of TAI but TA(k) has essentially no constraints. -zefram _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
