According to IGS Mail Message 651, there was a significant gap in the data
from ALGO on day 169. We have changed our reference clock to FAIR on the
following day, 170, to accomodate our 30-hour arc processing strategy.
Satellites PRN01 and PRN21 were poorly modelled on day 170. We have excluded
these satellites on this day only.
According to the file nanu1994.mes obtained from the IGS CBIS, PRN12 is
unusable beginning day 168 for an indefinite period. We have deleted this
satellite from our processing for days 172-176.
On day 172, we include data from a new station, EISL (Easter Island, Chile).
The following nominal coordinates were assumed, and the station locations were
estimated (unconstrained) this day:
X = -1884949.4272 m, Y = -5357598.7566 m, Z = -2892889.1879 m
Days 171 and 176 were processed prior to our updating of IERS Bulletin B
nominal values. This is manifested in the apparent discontinuities in UT1R-UTC
on these days.
Lastly, various data problems required that some days be re-processed this
week. In order to expedite the analyses, a well-distributed subset of no more
than 20 stations was used for days 173-175 (Jun 22-24).
WARNING: Data from PRN01 and PRN21 excluded day 170 (Jun 19).
WARNING: FAIR (not ALGO) used as reference clock for day 170.
WARNING: Data from PRN12 excluded days 172-176 (Jun 21-25).
In the following table, UT1R-UTC are the assumed nominal values from IERS
Bulletin-B predicts; estimated LODR values are also included. See IGS Mail
Message 97 for details.
