Preparation for Observing
Users allocated VLBA observing time, either on fixed dates or on a dynamically-scheduled basis, will be sent instructions for preparing observing schedules. Approximately 65% of all VLBA observations are scheduled dynamically, based on array and weather conditions predicted 1-2 days in advance. Most VLBA observations are scheduled using the NRAO program SCHED (Walker 2011). Help with preparing VLBA observations is available through the NRAO Helpdesk.
