My (limited) experience with sending L1/L2 data to both NRCan and OPUS is that there is a noticeable improvement from the "ultra-rapid" to the "rapid" results a day or so later. The difference from "rapid" to "final" is barely noticeable (but is real). _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
