The data in this dialog come from the "*._os", "*._ww", "*._r", and "*._w" files computed by the MODFLOW observation process. The computation from MODFLOW will include any observed flows combined with the observed heads to calculate a single error value. In a transient model, the error value includes all of the observations at the various times. The error shown in this dialog is different from the error found in the [[GMS:Error_Summary_Plot|Error Summary plot]]. | The data in this dialog come from the "*._os", "*._ww", "*._r", and "*._w" files computed by the MODFLOW observation process.
