Team reports




  • Last Week:
    • Meetings in Tucson
      • Pointing - M. Wagner, D. Thompson, etc.
      • Acquisition Camera Design & Implementation brainstorming- J. Kern, D. Thompson, John H., Christian
    • ARGOS pointing performance (first look)
    • Collimation model performance (Feb, March)
  • This week:
    • Pointing Log data evaluation - closer look to see if there might be problems with input data to TPoint
    • Collimation modelling equations (E-time prep)
    • ARGOS IE/CA analysis (from telemetry)
    • Begin Acquisition Camera design writeup for HW transition to Eng Team.


Last week I worked mostly on the LBC script bug. Alsmot all was XSLT work


jastier-dev now has 16 GB. Thanks Stephen!

Last week - Binocular planner, mostly copointing. Done except for one absorb case.

This week - make sure it can pass all tests from DS.


Last week:
  • OVMS+TT meeting - the most interesting part for me was the discussion about synchronizing time between AO and OVMS
  • SVN diffs with OAC code to make sure current version is tagged before I check in the new HK code
  • Follow up of shutdown tasks - found humidity sensor calibration info and passed it on.
  • In Tucson on Friday:
    • configured 2 new spare iBootBars for LBC
    • meeting with Dan and Mike and then with John about what and where to put alarms in OAC upgrade
    • OVMS discussion with John - code update required and there's some fiber labeling on the mountain to check

This week:
  • OAC HK upgrade
    • Add client for setting warning thresholds
    • Start alarm handling - direct to EPICS
    • Clean up before checkin - error-handling, no test code, etc.
  • Meeting with Fernando for LBC controller upgrade
  • real-time code update for OVMS for engineering time (IT 7170)


  • management OC, WPC, ISP interview
  • meeting Argos, OVMS+, LBTI post run
  • follow up VM SSD, NetBrain,SSP, AdSec PB plan
  • iteration and prototype git, rpm, Jenkins CI, rpm, yum server (ctd.)
  • issuetrak api - node.js scripts, API does not expose 'Last Activity Date', back to selenium
  • LBC controller upgrade [re]kickoff
  • responsibilities and assignments draft
  • techtalk#1 git//ci/rpm/kickstart


  • Time To Live - Az/El axis working, problems with rotator code (will spend at least a part of this week on it)
  • DUT1 final testing, Saturday engineering
  • Missing PCS documentation??


  • Packaging support scripts (e.g, TCS simulator) -- what repo, and how to split them -- part of a common build?
  • RPM packaging web applications, with consideration of SE-Linux.
  • Using "dot" to draw complex diagrams.
  • turning on process accounting on obs computers with the eye on who is running what? Maybe go back over shell histories?


Last Week:
  • Meeting/diucssion about 4D related, OVMS+, powerBack plane and ARGOS
  • Sent detailed rip information to LBTI
  • Skip frame threshold discussion
  • Read the MG document and give feedback to MG
  • Discuss the flat apply issue on Adsec

This week:
  • Add log information for TT LUT
  • finish reading the MG document
  • write the low level communication code for PowerBack plane


  • General browse of observatory information.
  • Look at and study a bit of the SVN AO code, particularly trying to understand how the logging works.

Action items

  • NetBrain (David - schedule demo)
  • VM/SSD (David - followup meeting)
  • binoccular planning follow-up (Joe, Doug, Matthieu)
    • do we need the same resolution as TCS in OT? maybe the code complexity just Ok
  • Core A (Stephen - follow up, eng night?)
  • Argos (Andrew - s/w handover doc progress, schedule meeting)
  • Logging (Yang - requirements, design, concepts iteration - schedule meeting) - TCS lib (PK), other info in the Twiki (TBD)
  • SSP final draft (Matthieu)
  • techtalk#1 (Matthieu)
  • github user details, responsibilities, etc. - consult emails, meeting minutes, MB if needed (---)
  • file vacation and time off in time

Open discussion

  • pointing / collimation (DS) Thinking of putting up together a new camera/telescope to isolate mount vs other error source
