Synopsis
Send image of the fit results to ds9.
Syntax
image_fit( [ id, [newframe=False, tile=False, deleteframes=True]] )
Description
Sends the fit results of 2-D image data to the imager--by default, ds9. The images shown are data, model, and residuals, by default each in a different tile of the display.
- id - the id of the data set to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
- newframe - add a new frame; default=False
- tile - tile image frame; default=False
- deleteframes - delete preexisting frames; default=True
Example
sherpa> image_fit() sherpa> image_fit(1) sherpa> image_fit(1, newframe=True, tile=False, deleteframes=True)
The image_fit function can be called with no arguments, in which case fit results associated with the default data set are sent to ds9. By default, images of the data, model and residuals are sent to three new frames, and the frames are tiled for display. The parameter "deleteframes" indicates whether or not any preexisting frames should be deleted before three new frames - containing data, model and residuals - are created.
