Guide log analyser

Guide log analyser for long exposure astronomical imaging. For long exposures of the night sky the mount is guided on a star using a second guide telescope and camera to compensate drift.

This program reads guide logs of the CCDciel and PHD2 guide program, measures what the mount does and simulates the guider with other settings. It then advises the gain, hysteresis and minimum pulse (CCDciel) or the aggression, hysteresis and minimum move (PHD2 Hysteresis algorithm) that give the smallest guiding error. It also reports on polar alignment, periodic error, Dec backlash and sudden jumps of the mount.
