KCOR COMMENT BY berkey: Mon Jun 15 18:27:49 GMT 2026
The kcor alignment algorithm with 80 points was oscillating/hunting which was causing rocking under the occultor, so the number of tracks was reduced to 5 as a temporary solution since it seems the algorithm probably needs some sort of dampening/derivative gain.
