When the DCR tool GUI is started, it shows the available scans in the ``Scan'' listbox. When a scan is selected with the mouse, the ``Receiver'' and ``Phase'' listboxes are filled in with the relevant choices, and the text area is filled with some header information. The Cal value can be set in the given entry box. The TPnC Cal entry value is not yet used. Raw counts can be plotted for a given phase by selecting a Receiver and Phase and then clicking the ``Phase'' button in the ``Plot v. Time' row. Antenna temperature and source temperature can be plotted likewise, when appropriate.
The ``Plot'' row offers four buttons to plot the data counts vs. RA, data counts vs. Dec, antenna temperature vs. RA, and antenna temperature vs. Dec, respectively. The ``Procedures'' row allows easy access to the automated routines for reducing pointing and focus scans. The ``Point1'' routine plots a single scan's data as a function of RA or Dec offset, fits a baseline and gaussian to the cross scan, and returns information about the Az and El offsets determined from the scan. ``Point2'' and ``Point4'' work similarly on sequences of 2 or 4 scans in a pointing observation. Select the first scan of the sequence in the Scan listbox, then choose the desired pointing function.
Along the bottom of the DCR tool GUI are several more control buttons. The ``Update Scans'' button is used to update the scan list when the filler and DCR tool are being used in the online mode. The ``Clear Text'' button is self-explaining, and the ``Summary'' button lists some information on the scans in the scan listbox. The ``Ready'' button is a status indicator, and the ``Dismiss'' button shuts down this particular instance of the DCR tool.
