Installation of the RR to work in a new bin recosntructor. Reaquire pupil and reconstructor for Bin1.
Test of the reconstructor during the night. We have seen the intermittent failure of the use of this reconstructor. The secondary RIP with the inner ring jumped out. Seeing variable 1.1"-1.7". Secopndary telemetry dayta are saved for post-processing analysis and investigation of the problem.
Daytime activity to work in a new reconstructor for bin1. This new reconstructor will be tested during the night.
New reconstructor for bin1
seeing variable 1.1"-1.5"
We can see that the new and old reconstructor are giving some problems. The inner ring of actuator jump up and force the shell to RIP. Many presets have been sent and secondary telemetry data are saved. analysis of the data didn't reveal a clear issue which trigger those secondary events. An issue is the pupil separations that change during night time and daytime RR. Daytime RR is 36 pixel separation adn during the night is 35.5 or 35.7 pixels.
At the end of the night we went up to the W-Unit to check is something is loose the board, but seems everything is tide and solid.
