The Add Component Dialogue

The Add Component dialogue is used to add new components to the model. It will appear when you select the Add Component command from the edit menu.

Select the component type (Point, Sphere or Gaussian) using the option menu at the top of the dialogue and fill in the component parameters in the fields in the middle part 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 6.1: Constraints on the Parameters for a New Component. 

Click on OK or Apply to create a component. 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 6.1. A new component will only be created 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 component is created. If you clicked on Apply the dialogue will remain in place allowing you to create more components.

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