==== Report for the week of 3/25 ====
 * Mark and Fabian helped Fujii-kun with PR2. The problem turned out to be two broken flags. Hirata-san drew up a design for a jig to help reglue the flags in situ.
 * Fabian documented the height budget for the Type B suspension in the wiki ([[KAGRA/Subgroups/VIS/OpsManual/TypeB/SR3Data]] etc).
 * Terrence wrote up the final version of his OL diagonalization scheme.
 * Terrence worked on L2P decoupling for the TM.
 * Terrence and Mark edited the Type B Guardian to put turning on the payload damping later in the sequence, to help ensure that the OSEMs are not touching by the time they're needed (which can happen if the BF is buoyancy compensated for vacuum but the suspension is vented).
 * Mark started on a big tidy-up of the cleanbooth.
==== Plan for week of 3/25 ====
==== Report for the week of 4/1 ====
 * Support of Type Bp
  * 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.
