image_source

Synopsis

Display the source expression for a data set in the image viewer.

image_source(id=None, newframe=False, tile=False)

id - int or str, optional
newframe - bool, optional
tile - bool, optional

Description

This function evaluates and displays the model expression for a data set, without any instrument response.

The image viewer is automatically started if it is not already open.

Examples

Example 1

Display the source model for the default data set.

>>> image_source()

Example 2

Display the source model for data set 2 in a new frame so that the data in the current frame is not destroyed. The new data will be displayed in a single frame (i.e. the only data shown by the viewer).

>>> image_source(2, newframe=True)

Example 3

Display the source models for data sets 'i1' and 'i2' side by side:

>>> image_source('i1')
>>> image_source('i2', newframe=True, tile=True)

PARAMETERS

The parameters for this function are:

Notes

Image visualization is optional, and provided by the DS9 application.
