Oscillations / Earthquake info

mar 2006


Intro:

    Oscillations can be measured with tilt sensors, tiedown tensions, encoder positions, total power  variations of astronomical sources. Often times it's not obvious where the oscillation is coming from (eg. an oscillation in the total power when tracking a source could come from the rotary floor, feed tower, platform caused by drive system motors, platform caused by tiedown jacks, etc...
    This page gathers together the info on oscillations that has been scattered over a number of pages.
