Description
This tool is an in-house suite of functions intended to be used exclusively with digital continuum receiver (DCR) data from the Green Bank Telescope (GBT). The tool consists of 2 GUI components: A panel of buttons which offers an interface to some of the common functionality, and a plotter window which displays results when applicable. The complete functionality of the dcr tool is available from the command line interface. The tool is aimed at satisfying the requirements for commissioning the GBT, primarily, but it may find use as a general purpose continuum analysis tool as well.
