The system is designed for mounting at the prime focus of the National Radio Astronomy Observatory (NRAO) 11 m antenna at Kitt Peak, Arizona, and is suitable for the study of rotational line spectra of interstellar gas molecules. Currently the operating frequency is in the 90--140 GHz band where the double sideband system noise temperature is 250 K.", optnote="Recommended by Klapwijk", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=927), last updated on Tue, 24 Jun 2014 17:17:23 -0500", doi="10.1063/1.1686288", opturl="https://doi.org/10.1063/1.1686288" }
