== Progress report ==
=== Type-A ===
==== Past week report ====
 * sc-performance check by YF.
https://github.com/YoshinoriFujii/Weekly-task/issues/23#issuecomment-535775755
 * GAS servofilter reshaping [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=10695|klog#10695]]


==== Plan for coming weeks ====
 * measure decay time constants 
 * check axis between IP and Xarm etc 


=== Type B ===

==== Report for the week 23-09-2019 ====
 * Terrence  modified the real-time model in order to accomodate hierarchical  actuation from the interferometer sensing and control system (ISC). The  modified model has not been installed. See klog entry [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=10692|10692]].
 * In  previous meetings it was reported there was a problem with the medm  screen or real-time model in the components related to IP LVDT  correction with the seismometer signal. In reality a trivial operation  was still required. The apparent problem has been fixed now and we can  proceed to implement the sensor correction in SR2 when we have the time.

==== Plan for next week ====
 * If we have the time it  would be good to implement the sensor correction at least in the BS and  test it in bad weather conditions.
 * Commit the changes that Terrence made to the real-time model.

==== Vacation/Travel Info ====
Friday next week late in the afternoon we have the KAGRA ceremony.
