Attached is a first go at precalculating Hp using haversine Doniol sight reduction and an 8 inch circular slide rule. The Hp table has 10 entries every 4 minutes with a 10:00 am arrival at Catalina Island tomorrow. It took less than 40 minutes to generate the table in a production line fashion. Results are within 2' on altitudes and 1° on azimuths.
