The Point-Wise method of taking data requires specifying two times; viz,
the settle_time - the time in seconds between the antenna reaching the
demand position and the start of integration - and the sample_time - the
time in seconds spent sampling the inclinometers. The tests below were made at
(az,el) = (270,89.9) with various combinations of settle-time and
sample_time, and the data analysed for means and standard deviations in each
inclinometry output channel (in mV) :

These data suggest settle_time = 4
and sample_time = 2
as optimal values.
