Lesedi HRS Project Wiki

This wiki is for construction of a high-resolution spectrograph on the 1-m Lesedi telescope in Sutherland. We anticipate future wikis for the user manual and for technical support.
The SAAO and Christian Schwab (Macquarie Univ. and AAO) are collaborating on the project.
The instrument is based on a design that Christian modified from NEID, an innovative HRS for use on the 3.5-m WIYN (https://neid.psu.edu/). We are hoping to reach a few m/sec accuracies for radial velocity measurements on Lesedi.
