The Rating Data Table (CWMS Rating Editor Window) allows you to view the rating curve data in a tabular format, with each column containing the corresponding data for each of the independent and dependent parameters. The Effective Date for the selected rating curve is displayed (Figure 1). The Rating Data Table layout differs for a rating curve with a single independent parameter (Figure 1) and for one with multiple independent parameters (Figure 2). For rating curves with only one independent parameter, the Rating Data Table will display all the rating curve data with the independent parameter in the second column and the dependent parameter in the third column. The first column of the Rating Data Table is filled with nodes for each point on the rating curve. If a parameter is set to elevation, the vertical datum information will show in the column header, next to the unit.



For rating curves with multiple independent parameters (Figure 2), multiple columns are present for every independent parameter. The arrangement of the independent parameters columns follows the order of entry for the independent parameters.

Values in the Rating Data Table are editable and are synchronized with the Rating Plot. The Rating Data Table also allows the selection of multiple points on the rating curve when using the Point-Editor Tool of the Rating Plot. This allows the graphical editing of the multiple-points of the rating curve data by moving them altogether.
