   6 %    get_Q_value -           calculates and outputs the Q value and decay 
   7 %                            constant for a suspended optic.
   8 %
   9 %    Set_Q_value -           sets the Q value of the mode cleaner 
  10 %                            optics to a specified value.

  14 %    do_cmd -                will repeat ezca or tds commands in the case of a 
  15 %                            segmentation fault.       
  16 %
  17 %    freq0 -                 outputs the resonant frequency for any degree of
  18 %                            freedom for any of the mode cleaner optic.
  19 %
  20 %    fit3 -                  fits a ringdown curve
  21 %
  22 %    timer_set_Q1 -          turn off the lock, apply the
  23 %                            offset to the mirror, wait  30 s and then start
  24 %                            the function data_collect_set_Q1.
  25 %
  26 %    data_collect_set_Q1 -   called by fun_SetDegQ1 in order to get data, 
  27 %                            create time vector and turn off the offset that 
  28 %                            was used to kick the mirror.
  29 %
  30 % Change settings for the suspended optics for different 
  31 % measurements.
  32 
  33 %    Set_Screen -             Turns on all of the LSC, ASCPIT and ASCYAW
  34 %                             inputs and outputs and off all filters and
  35 %                             limits for the mode cleaner optics and sets the 
  36 %                             offsets to 1000.          
  37 %
  38 %    Restore_MCSettings -     Restores the settings of the mode cleaner optics 
  39 %                             that were changed when the script Set_Screen
  40 %                             was run.
  41 %
  42 %    Restore_Optic_Settings - Restores some of the settings of all the optics.
