According to the file gpsn2.txt obtained from tycho.usno.navy.mil, PRN22/GPS22
was scheduled unusable for up to 8 hours (repositioning) on May 27 (day 147),
beginning at 09:30 UT. Thus, data from this satellite have been deweighted for
the analysis of that day.

WARNING: Due to the maneuver of PRN22/GPS22, data from this satellite have               been deweighted for day 147 (May 27).
