IM4/PR2 ASC loop tuned up, POP_RF18_I is higher
-
I tuned up the input pointing ASC loop which I closed yesterday (alog 14162).
-
see the attached for the loop parameters.
-
Locked PRMI and found POPAIR_RF18 at a high value of 200 uW.
-
One difference from the past is that IM4 had been servoed to a small bias in pitch (~11000 urad) by the IM4/PR2 loop.
