Task Assignments

High priority tasks

Need to get results for discussion at next meeting in one week

  • DFB & JSY: Assign working value for overall image quality requirement
    • Note we will use the working value until it can be refined by simulation
  • DFB: Assign range for pixel scale
  • ADR & CAH: Think about how to apportion image quality budget
  • ADR & CAH: Nominal stability budget
  • XS: Understand space envelope, optical components & make CAD drawing
  • XS: Initial studies of achievable stability
  • MF: Thermal analysis of camera in box
  • JSY: Make corrections to appendix of FTT technical requirements document

Lower priority tasks

  • ADR: Optical design using off-the-shelf components
  • EBS: Liase with ADR about possible sources for off-axis paraboloids
  • EBS: Chase Princeton for mechanical drawings of camera
  • JSY: Photon rate calculations
  • MF: Get available environmental statistics as background information
  • DMAW & MF: Start thinking about test arrangements

Next Meeting

A follow-up meeting to discuss initial results from the high priority tasks will take place at 14:00-16:30 on Friday 7 May in the Ryle Seminar Room.
