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

Tasks identified February 2025:

Spectrograph

1. continued work on alignment, esp with “point” source
2. installation of prism
3. installation of camera
4. installation of focuser + detector
5. testing with calibration source? solar source?

Calibration channel

1. assembly of relay optics / stage at focal plane
2. development of calibration source : Shelyak possibility? Selectable sources by stage? Integrating sphere?

Fiber
