Was the solution using the NRCan hourly's or the IGS Rapid products ?
(It should say in the email response or the <foo>.sum file: the
'Satellite orbits/clocks' lines seem to have 'emu', 'emr' or 'igs' for
the NRCan hourly/UltraRapid, Rapid and Final solutions respectively).
Submittals less than a day after the observations in the RINEX file
seem to result in the use of the Hourly/UltraRapids solutions.

Cheers,
Tim
