On 940525 the decision to purchase two new AGI inclinometers was made, and
following tests in Hilo they are currently being installed in the old
locations.
The choice of ultimate location for the new meters is still subject to test.
DGH A-D converters are not yet available for all the channels and the system is
likely to be tested initially without temperature data for at least one
inclinometer.
The software for data acquisition and analysis is also likely to undergo
substantial revision in order to facilitate rapid production of a track model.
The input to the data acquisition software is likely to be a file of azimuths
(generated off-line) in order to facilitate variable resolution. (The utility
of the ensuing variable-resolution model within the TEL task will need
addressing). Settling times and
integration times will depend upon perfomance, and the strategy of data-taking
will depend upon the reliability of the new devices, but hopefully will
involve less convoluted referencing than before. This will speed up
the entire process and, in the best possible case, i.e. where
a) device stability enables a single sweep around the azimuth
circle, i.e. with
b) no reference azimuths, except those in the overlap region, and
c) general 1degree resolution, but 0.1degree resolution around
56 jumps, and
d) short, say, 2
wait and 2
integration times
then the entire dataset might be obtained in 2.5 hours.
The production of a new track model every week may be quite feasible.
