===== Schedule =====

A high-level picture of the construction project schedule as of August, 2023 is shown here.

===== Update / item tracking  =====

Tasks identified February 2025:

Spectrograph
  - continued work on alignment, esp with "point" source
  - installation of prism
  - installation of camera
  - installation of focuser + detector : any parts needed?
  - testing with calibration source? solar source?

Calibration channel
  - assembly of relay optics / stage at focal plane
  - development of calibration source : Shelyak possibility? Selectable sources by stage? Integrating sphere?

Fiber
  - getting long fiber run + ferrule. All circular fiber? match 125 micron cladding or not?  Fusing 50/75/125 micron cladding onto other 50 micron fiber at focal plane side?  Fusing hexagonal fiber onto circular 50 micron fiber at ferrule side?
  - running fiber through conduit

Spectrograph room
  - legs for table
  - insulating box for spectrograph
  - making room in APO room 
  - confirming power (UPS) and Ethernet
  - relay/thermocouple control/computer packaging
  - location of pump
  - more thermocouples for monitoring instrument

FPU box
  - cover
  - cabling

Dome
  - lower slit control
  - packaging of dome control
  - spare computer and Raspberry Pi?

Software
  - interfacing Aarhus with APO
