Radio Noise Maps Unit

In 1957 Donald H. Menzel produced a set of radio noise maps under a contract between Harvard University and the Dept. of the Army, Signal Corps Procurement Office. These maps were specially designed charts in the form of a planisphere, with transparent sky maps of levels of radio noise which rotate over a grid representing the various altitudes and bearings in the visible sky at the observer's latitude. Bracewell acted as a consultant to Menzel's project. This unit includes the radio noise map set.
