A major upgrade of the JCMT Inclinometry System occured in the summer of 1994.
This is a report on the new system, including a summary
of the problem addressed by inclinometry, the newly acquired hardware, the
installation configuration, the new data acquisition and analysis software,
plans for the future, and, throughout, the results of the first series of
measurements.
The results presented here may be considered first epoch results against
which future measures may be compared. Inadequacies in the first
series of measurements became obvious during the subsequent analysis and
during the compilation of this report, and future versions of this report
will reflect extra work done since the end of September.
A comprehensive description of the old inclinometry system and the rationale
behind the techniques used prior to 1994 are given in the document
Inclinometry - The Past and Future, JCMT/IR/000.0. Much of that
document is still valid; although our appreciation of the interaction
between the antenna and track has improved since the installation of the new
system. A brief summary is given here to help set the scene.
