Quick 37m User Tutorial The following is a quick-start tutorial for the 37m telescope. It is not intended to take the place of the Umbrella tutorials and other manuals but is intended to be used as an aid when learning to begin an observing session.

Therefore it covers information about logging in to the 37 meter pointing computer known as “Fourier” (including remote login using a Secure Shell – SSH), setup of the radiometer using Umbrella commands, and brief explanations of observations to conduct a measurement of system noise temperature, initial pointing calibrations and a focus procedure.
