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
