CLIMB Noise Tests 2010JUN
From Monnier Group Research Wiki
on UT 2010Jun10, we took some test data on a K=XX mag source using 500Hz SYNC and 500Hz NORM on CLIMB to compare the noise properties. We also put in the H-band filter to help estimate the observed K band background counts. Lastly, we compared this to the NIRO performance, both noise and throughput from 2009 June.
Conclusions:
1. CLIMB has 50% less throughput than NIRO. One can see the Telescope -> Pixel Map does not follow the expected flux distribution, strongly suggesting there is some misalignment presently.
2. NORM mode is worse than SYNC mode. compare also 250Hz to 500Hz NORM.
