drift' to checked and specify the file name in the 'Configuration block'. The file format is a
plain text with two columns with numbers - deviations along RA and DEC.
Next you have to specify parameters in the 'Control' tab. All parameters are defined
separately for each axis RA and DEC.
These parameters are:
1. Enable directions - enables or disables the use of calculated axis corrections. All is
enabled by default.
2. Accumulate frames - enables the averaging of the coordinate values, using N frames,
and the transfer of corrections at the end of the averaging. Set to 1 by default, could be
changed when using very long guiding focal lengths.
3. Proportional gain - is the coefficient of the proportional term in the PID control. May be
precalculated in the 'Info' block by default.
4. Integral gain - is the coefficient of the integral term in the PID control. Set to 0 by default.
5. Derivative gain - is the coefficient of the differential term in the PID control. Set to 0 by
default. Disabled in this version.
6. Maximum pulse - the maximum duration of the correction pulse. Limited by the specific
type of the actuator. Set to 5000 ms by default.
7. Minimum pulse - the minimum duration of the correction pulse. Set to 100 ms by default.
8. Avg.frm. - disabled.
