The CDF document references these IERS Conventions <http://www.iers.org/nn_11216/IERS/EN/Publications/TechnicalNotes/> TEMPO 2 reducing pulsar timing observations <http://www.atnf.csiro.au/research/pulsar/ppta/tempo2/> Much of that math, the 4-transforms, the gravitational potential expansions, the time ephemeris, the ionization delay, depends on somebody's estimate of what is, in effect, weather in the universe at large. By comparison leap seconds are trivial. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
