zero_rotcor
Use the current rotcor readings as the zero point of future rotcor corrections.
- Arguments:
- (none)
- Example:
- The following example tells the tracker to read the current
rotational corrections, record them in tracker.zero[0..1] and
use them subsequently as the zero points of the tracker.rotcor
register.
zero_rotcor
- Context:
- As documented for the rotcor command,
the rotcor correction is composed of two components, measured
from rotation meters. These meters have arbitrary zero points
which potentially change with time and temperature. This command
allows one to zero them relative to the current readings. We plan
to do this at a standard elevation.
Note that if this command is used when the rotcor correction has
been disabled with the rotcor command,
the zero points will themselves be set to zero.
