Wait for timer	Read GS refAD from OLDB	Calc GS observedAD	Read Target observed AD from trk
Calc radius,angle relation of Target and GS on sky	Write r, angle to OLDB	Calc target observed AD	Write observed AD to OLDB
Call acmProbe:acmSendRefs	add deltaAD to refAD	Convert CCD xy to alpha/delta	deactivate atp Loop
Write refXY in OLDB	Calc new refAD from refXY	Read actual probe XY	Add deltaXY to actual XY
Call PRSETXY	starSelected=FALSE	Get actual positions	protect move
calculate new position	Set new position	check error OUT_OF_FIELD	Set alrma gp out of field
