211: X Data Domain

It is possible to select a rectangular sub-area of a gridded/station input dataset. The domain is specified by setting its latitudinal and longitudinal limits. Once set, the number of gridpoints in a gridded data analysis will be automatically reset on the CPT Window. For a station dataset, the number of stations on the CPT Window will continue to show the total number of stations in the dataset as originally specified. This menu item is available only if the input dataset is not defined as unreferenced. The program automatically prompts for the domain settings when a geographically referenced (gridded or station) input file is opened, but this menu item allows the domain to be reset without having to re-open the file. Note that changing the X domain will require CPT to reset if results have been calculated.
