There is a pre and final hardware limit switch for the upper limit and the lower limit on each jack. The actions of the limts are:
Whenever we survey from AO9, we use the current encoder values to determine how to move the tiedowns. So by definition, after an ao9 survey, the tiedown positions are now correct. This is not quiet true since we have been using the focus curves to determine the focus rather than the ao9 survey value.
The table below has the measured values of the position using encoder and tape measure. Encoder values 24 inches is when the jack is fully retracted (high tension). 0 encoder inches is when the jack if fully extended (low tension).The cols in the table below are:

The software limits used to limit the
requested positions are .2 inches inside the final limits. They
are in the file /home/phil/h/tieProg.h
