==== Report for the week of 4/15 ====
 * Fabian debugged a dead stepper on SR3 (broken driver channel) and a dead geophone on SRM (unplugged cable). He made another update to the table used by the Python script for the stepper driver MEDM screen to reflect the remapping.
 * Fabian monitored the pumpdown and he and Hirata-san did post-pumpdown checks of all the suspensions. They were all healthy.
 * Hirata-san participated in the health checks and learned about the computer systems.
 * Mark did major revisions to the MEDM menu on the OVERVIEW screen with scripts for making `safe.snap` files and snapshots of setpoints. He made the `safe.snap` files in directories under `/opt/rtcds/kamioka/k1/target` into symbolic links to files in `/opt/rtcds/userapps/release/vis/k1/burtfiles`, alongside the setpoint files, so that they could be backed up to the SVN (as at LIGO).
 * Mark did major updates to his `vistools.py` Python package for manipulating the suspensions (based on his LIGO `sustools.py`). He added entries for Type B suspensions to the internal database and added commands for manipulating SET and DCCTRL blocks. He also added commands to simulate pressing on the `CLEAR HISTORY` and `LOAD COEFFICIENTS` buttons.
 * Mark started updating the `TYPEB.py` Guardian definition file to use `vistools.py`. So far only the `ENGAGING_IP_CONTROL` state has been fully rewritten and tested, but other states will be simple adaptations. It should be easy to do Type A and other Guardians in the same style.
==== Report for Golden Week ====
 * Mark monitored vent and pumpdown, and worked on vistools.py.

==== Plan for week of 4/22 ====
 * Mark, Terrence at Kamioka Mon-Fri.
 * Fabian at Kamioka Mon-Thu.
 * Work with Lucia to do blending of the IP LVDTs and geophones.
 * More Guardian improvements.
  * Improve `vistools.py` (add more useful functions; add docstrings; add support for Type A/Bp/C; create test suite).
  * Finish and test new Guardian code using `vistools.py`.
  * 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).
 * Work on Type B paper.
 * Tidy up.
  * Gather and clean tools.
  * Gather and organize unused parts and fasteners.
==== Report for the week of 5/6 ====
 * Lucia and Terrence got the blending working for the IP LVDTs and geophones.
 * Terrence and Mark modified the models and MEDM screens to add a new IP block, IDAMP, for damping using the blended signal with inertial information, and a new DAMPMODE block for ramping smoothly between IDAMP and the old DAMP.
 * Mark worked on vistools.py, improving the support for cdsMuxMatrix blocks (e.g., OSEM2EUL) and adding support for cdsRampMuxMatrix blocks (e.g., the newly introduced DAMPMODE). He also created two sets of unit tests, unittest.py and unittest.sh, for the two modes of use (as a Python module in other Python programs, and as a command-line utility in bash).
