Engineering first light with three colour simultaneous imaging system-- Ryosuke Itoh, Kenji Kawaguchi, and Yousuke Utsumi.
Quick look
- With the z-position of 22000 (2.2mm), it looks like the focus is ok on Rc/Ic band. The nominal position is 2mm ranging between 0-4mm. We confirmed that manufacturing were good as desinged.
- The camera for U-channel was different model than others. The prepared software didn't work with it.
- The current patchy software which I spent only one day to make was able to control remaining CCDs but not able to control them simultaneously. Still need check. link to code
- We saw communication error to the telescope during reading out. These also use USB. It might be caused by heavy traffic.
- After taking this exposure, the environmental humidity was getting to be high gradually. We abandon tonight observation.
- We have not yet tested the alignment and the performance of the correctors.
