AO Telemetry

Telemetry is taken during the real-time loop, within rtc2.c. Data is stored in succesively numbered Data_xxxx.fits files. The data is mapped as follows.

The telemetry array within Data_xxxx.fits is 4097 columns each of which is a vector with 1382 elements.The 1382-vector contains the values of internal measurement and state variables at the sample time associated with the column.

Note, the first data vector is bogus (there for technical reasons having to do with the data collector), and should be ignored.
