The Digital Continuum Receiver (DCR) is used for making continuum observations. These observations include, but are not limited to, telescope pointing and the production of beam maps. Continuum emission refers to broadband rather than line emission. Radio continuum emission is the broadband radiation emitted in the radio part of the spectrum by celestial objects. The intensity (brightness temperature) typically varies relatively slow as a function of wavelength (or frequency). This is in contrast to the narrow emission lines (spectral lines) produced at characteristic frequencies by atoms and molecules. As previously stated, continuum observations are typically used to make point source flux measurements to aid in computing astronomical telescope pointing corrections. Pointing is done to ensure a telescope is accurately positioned to receive the faint emissions from the celestial object to be examined. The DCR can also be used to map extended radio sources such as galaxies. See Figure 1. These "beam" maps are based on a total power signal output. Continuum observations can be made with all GBT receivers. A depiction of the different types of science involving continuum observations, and as noted by frequency, is shown in Figure 2.
