  • Last week
    • Tested high priority LUCI issues with Jenny. Found that most of them appear to be problems with RTD Aladin instance and/or threading (event thread lockup).
      • The observed problem with the automatic slit alignment (IT 7642) was confirmed and may require on-sky time to fix.
    • Began investigating LUCI threading and Aladin issues.
    • Thoroughly re-read LUCI handover documents in Google Drive, now that I have a better understanding of the instrument.
      • I now understand what would be needed to test running LUCI from lucix; this is a topic for either a LUCI downtime (as discussed during the All-Hands) or 2022 Summer.
    • Set aside the ahs-luci integration and IT 8454 for the time being to work on the LUCI code fixes, which have a greater observing impact.
  • This week
    • Begin fixing and testing LUCI threading and RTD Aladin instance.


  • Post-vacation catchup
  • Jim's issue down to bad dock?
  • Ester Marini stuff
  • Got all parts for backup server upgrade, will find a time to come in
  • MS Server should be sorted out; waiting for receipt of license
  • Word on EOY expenditures?


  • Previous:
    • Some MODS stuff discussion and fix attempt (modsIDL).
    • Tested Python 2.7 inotify programs (should work okay, but a few things to discuss).
    • Start to work on a MODS WCS program.
    • Initialized the new mods-obs repository (more tweaks to follow).
    • TMS meeting and some TMS data mining and analaysis.
    • Worked with Paul on Argos swingarm test in TCS/OSS.
  • Next:
    • Continue some misc LBC/MODS things (modsAlign/IDL/WCS/new github repo etc).
    • Discuss a few issues about the Python 2.7 inotify program and then move forward to develop it.
    • More TMS data discussion and some software work.
    • Work with Paul on Argos swingarm test if we can get some telescope time.


  • Last week:
    • Added tool for getting data from AdSec diagnostic dumps to ao-datasystem.
    • OC investigation "data support" (cross referencing elevation, diagnostic dumps)
    • Continued getting familiar with ao-supervisor code, how and when diagnostic dumps are produced, deleted, backed up. Consulted Xianyu re: deleting of old diagnostic dumps.
    • AdSec gain=0 testing planning / AOG meetings
  • This week:
    • T-Th AdSec gain=0 tests.
      • Get familiar with Python/IDL communication to AdSec w/ICE.

    • Sending commands to D425 device causes the device to reset connection (terminal program works fine).
    • Selection of ARGOS swing arm on GUI won't "stick". This may be a deeper problem.
  • Next:
