Q&A
- Arc image is rotated in X,Y
Solution: power on the telescope.
- Program hangs up when you set up an exposure time lower than the integration time.
- The integration 'beep' keeps ringing.
Solution: Restart.
Solution TODO: code that it does not crash, neither repeat the beep, but just stops exposing.
Time when changed during the routine, is being read automatically.
- ifu window does not show on pylon
Solution: log off from pylon and log in again to restart all windows.
- The arc did not seem to manually adjust for the right exposure time.
- The telescope focus has a non-linear response to different focus distances. It seems to have a "dip" at some point and decrease, before increasing again.
The focus seem to vary quite a lot and it does resemble a random scatter with 0.02.
- When the seeing reaches about 3.5", the guider starts to fail.
- The centre of the IFU shown by the rectangle+circle seems to be shifted 400 pixels in X axis to the left. No major shift in Y axis.
