How do I use the DCT?

There is a lot of information here:

The general idea is that you don't use the DCT. The TO (Telescope Operator) uses the DCT and you use IGRINS.

Make yourself familiar with the building. Spend a little time looking at IGRINS, the helium compressor, and the changes to the DTP.
