To be able to get slits properly in focus with the HR camera the range over which the focus mechanism can move needs to be extended. This is planned to be done together with the installation of the science array and tests of the wheel bearings.
The design for a simple wavelength calibration unit should be decide, and the system should be installed and commissioned.
In the longer-term one should look at getting a new calibration unit with proper interface to the lamp with the corresponding header information. The final design will likely include a lid separate from the mirror cover petals which can be closed and opened quickly.
