Dynamic Scheduling Simulations Dana S. Balser & J.J. Condon
Based on ~ 3 years of weather data Total time: schedule 1 full year with 20% backlog 900 sessions x [1-5] TPs ~ 2700 TPs TP = [2-6] hrs 1.2 years Frequency coverage: 30% L-band and lower; 5% S-band; 5% C-band; 5% X-band; 5% Ku-band; 25% K-band (40% H2O); 10% Ka-band; 15% Q-band 10% H2O Spatial coverage: % all sky; 75% single source or region (1/3 in Galactic Plane (20% GC) ; 2/3 Extragalactic) 5% GC

Frequency Coverage Histogram of the number of sessions for 1 GHz frequency bins. White area: total number of sessions allocated Blue area: number of sessions executed
3
Sky Coverage Scatter plot RA vs Dec.
Blue plus signs: sessions available to run Red crosses: sessions that have been run
4
Frequency History Scatter plot of the session that have been run for a given frequency and time. No K-band sessions during the summer too much water vapor. Many Q-band sessions during the summer not effected much by water vapor. Effected by O2 and hydrosols. Also high Trcvr. Only a few Ka-band during the summer some effect of water vapor. Lower Trcvr so the atmosphere matters. Intermediate frequencies and low frequencies are not well balanced in time.
