 * Support of Type Bp
  * Mark made lots of Guardian improvements:
   * Used Guardian's timer functionality to drastically reduce the number of notifications during ramping.
   * Added new requestable states DCCTRL_ONLY and NEUTRAL (and associated transitional states) to facilitate testing.
   * Tidied up the code to use tabs consistently throughout for indentation.
   * Disabled the test for the IM-H coil driver WD (to work around the fact that only the relay in the chassis has been disabled, not the WD signals going to the BIO).
 * We opened the BS tank lid and offloaded a large IM-Y offset to F0-Y with manual adjustment of the broken yaw mechanism).
 * We opened the SR2 side doors and adjusted the V1 OSEM to mid-range.
 * Mark offloaded a large SR2 IM-Y offset to F0-Y.
 * Mark did health checks for BS, SR2 and SR3.
 * Fabian offloaded yaw from SRM and did the SRM health check.
 * Fabian updated the Python code for the stepper driver MEDM screen to reflect that two stepper drivers have different mappings to work around dead channels.
 * Fabian monitored pumpdown on Friday afternoon and will continue on Saturday.

 * Work with Lucia to do blending of the IP LVDTs and geophones.
 * More Guardian improvements.
  * Update vistools.py (formerly LIGO sustools.py) for Type B and KAGRA, and have the TYPEB.py Guardian use it where appropriate.
  * Modify RT models and/or Guardian to revert to the SAFE state under control in all but the most extreme emergency situations (rather than suddenly shutting off all output).
