The Modify Component Dialogue

The Modify Component dialogue is used to change the parameters of the selected component. It will appear when you select the Modify Component command from the edit menu.

Type the new parameter values into the fields in the working area of the dialogue. The fields all take floating-point quantities and will reject any character that can not be part of a floating-point number; it is still possible to type invalid floating-point (eg. `1.0.0') into the fields, however.

The flux density is given in Jy, offsets and sizes are given in milliarcseconds and position angles are given in degrees.

Table 6.2: Constraints on the Parameters for a Modified Component. 

Click on OK or Apply to apply the changes. The values in the fields will be checked to see that they are valid floating-point numbers and that they meet the constraints given in Table 6.2. The changes will only be applied if no errors are detected. If an error is detected, an error dialogue will be posted. If you clicked on OK, the dialogue will be dismissed when the changes are applied. If you clicked on Apply the dialogue will remain in place.

If you wish to dismiss the dialogue without modifying a component, click on the Cancel button.

As long as the dialogue is visible, it will reflect any changes in the selected component. If none of the components in the model are selected the dialogue will become insensitive, indicated by a stippling of the labels in the dialogue.
