Special purpose image display devices and techniques at the National Radio Astronomy Observatory

The NRAO has developed an image storage unit/control panel that greatly enhances the functionality and user‐friendliness of its image display computers. Described here are the hardware design and capabilities of this system. In addition, a selection is presented from an image display software ‘‘bag of tricks’’: various image display techniques that have been found to be extremely useful in the analysis of radio astronomical imaging data and may be of interest to those in other fields of the physical sciences.
