dynamic loading of td's from telescope motion.


    On 03feb10 a failed beam was found on the platform where tiedown 12 backstay cables attach to the the platform. To get an idea for how the tension in the tiedowns varies with telescope motion, 3 different projects that use repetitive telescope motion were selected  (a fourth day was also  included to show  typical tracking of sources).

    The projects were:

The plots show the tiedown tensions during these experiments (.ps) (.pdf):
