Comments (from YF, please feel free to rm this comments after reading:)

• Why not have a table/spreadsheet like the following somewhere as Yokozawa-san suggested? We definitly need much more fancy one and user-friendly one though. I could not find any other good idea now sorry. Could someone please work on it? The number of the people who want to use the interferometer is NOT one or two anymore.

  • mainly for day-time work and silent-run
  • maybe for requesting, or for showing the planned/allowed ones.
  • with proposer name and rough estimation of the necessary time slot (duration)?
