image_source_component

Context: modeling

Synopsis

Sends image of the unconvolved model component to ds9.

Syntax

image_source_component([id], name, [newframe=False, tile=False]] )

The image_source_component command sends an image of one, or a combination of, individual 2D source model components to the imager (ds9) to allow the user to quickly visualize the contribution to the full model being used to fit the data. The model components will not be convolved with any assigned PSF convolution models; the image_model_component command is available for displaying convolved model components. By default, the image is sent to the same frame and the frames are not tiled.

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")
name - variable name representing the model component
newframe - add a new frame; default=False
tile - tile image frame; default=False

Example

sherpa> set_source(2, const2d.c1 + gauss2d.g1 + beta2d.b1)
sherpa> fit(2)
sherpa> image_source_component(2, g1+b1)

Display in DS9 an image of the sum of the unconvolved Gaussian 2D and Beta 2D model components "g1" and "b1" assigned to data set 2 with the image_source_component command.
