HRS Throughput Estimates per Resolution Element

It is important for the PI to realize that due to the design of the HET the effective collecting area changes over a trajectory. Near the end of a trajectory the HET has half the collecting area that it has near the middle. As such two medium length visits centered on middle of a track could be more valuable than a single long visit. All throughput estimates are based upon center of track efficiency.

To see the effect of changing exposure times in a moving aperture try the HET Filling Factor Calculator.

We will adapt the old HRS throughput calculator as time and information allows.

Until we have the new one you can try our old HRS Throughput Calculator.
