 * Type B Past Week Summary
  * Mark (with Enzo) did initial TFs on the BF.
   * Did fixed-sine TFs on individual OSEMs at low frequency to check actuator polarity (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Set gains in the COILOUTF block to compensate for actuator polarity.
  * Mark (with Enzo) did a free-swing measurement on the BS after earthquake of 11/22 (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Results suspicious (noted by Shoda-san): too much difference between OSEMs - horizontal showing much less motion than vertical.
   * Possible rubbing in horizontal.
   * May need a trip to Kamioka.
  * Mark (with Enzo) made corrections and improvements to many of the MEDM screens (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Main overview screen was not generic in many places, and links to GDS_TP screens were broken.
   * ADC monitor screen referenced bad channels with LIGO-style names.
   * DAC monitor screen was not generic and did not support IM OSEMs.
   * Watchdog IM OSEM AC band limit filter screen was a copy of the TM one.
   * Watchdog TM OSEM AC band limit filter screen appears to be getting OL signals as input - needs model changes to fix.
   * The zoomed screens for IM OSEM centering were called incorrectly and did not work.
   * Various screens had LIGO-style channel names as labels.
  * Mark did a draft of D1603600-v12 reflecting the new assignment of IM OSEMs to DAQ channels (#4-9 are now V1, V2, V3, H1, H2, H3 rather than H1, H2, ...) from last Friday (the wiring was changed to reflect the model).
  * Mark worked on schedule.
  * Hirata-san
  
 * Activity report for week of 12/19
  * Mark and Fabian checked Hirata-san's drawings and parts/fastener lists for the SRM/PRM order.
 * [[KAGRA/Subgroups/VIS/VISMinutes/20161216|BF issue]]
  * Aso-san and Mark decided to have the BS bottom filter
