AHELP for CIAO 4.9 Sherpa v1

image_data

Context: visualization

Synopsis

Send image of 2-D data to ds9.

Syntax

image_data( [ id, [newframe=False, tile=False]] )

Description

Sends an image of the 2-D data set to the imager - by default, ds9.

  • 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

Example

sherpa> image_data()
sherpa> image_data(1)
sherpa> image_data(1, newframe=True, tile=False)

The image_data function can be called with no arguments, in which case an image of the default data set is sent to ds9. By default, the image is sent to the same frame and the frames are not tiled.

Bugs

See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
