  * Hirata-san procured the jigs for PRs and Takahashi-san tested one at TAMA.
  * Hirata-san cleaned up the flags for PR2 and Mark did the one for PRM.
  * Fabian helped Fujii-kun and Takashashi-san to reglue the flags.
 * Mark did a lot of maintenance on the MEDM screens:
  * Made the name of the suspension more obvious (no yellow text!).
  * Added rack temperature indicators.
  * Fixed the labels in the ADC screen (to reflect the LEN OL moving from ADC#0 to #1).
  * Fixed broken links.
  * Committed files to the SVN.
 * Mark did maintenance on the Guardian to make it give more helpful messages in the TRIGGER state. Formerly it only checked the user model watchdog and the coil driver watchdog, not the DACKILL, and gave the same generic notification for both. Now it checks all three and tells the user which need attention.
 * Mark tidied up the cables in the SR2 rack and returned a large pile of no-longer-used cables to the tent.
 * Mark started a !HealthCheck page on the Operation Manual wiki.
Fabian and Mark
==== Plan for week of 4/8 ====
 * Mark, Fabian at Kamioka Mon-Fri.
 * Help with Type Bp.
 * Health checks on Type B.
 * Monitor pumpdown.
  * 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.

==== Plan for week of 4/15 ====
 * Mark, Hirata-san at Kamioka Tue-Thu.
 * Fabian at Kamioka Mon-Wed.
 * All at f2f Meeting 4/19-21.
 * Post-pumpdown health checks.
 * Teach Hirata-san about the computer systems and control theory.
 * 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).
