AHELP for CIAO 4.6 Sherpa v2

image_setregion

Context: visualization

Synopsis

Sends a region description to ds9, where it is drawn in the current frame.

Syntax

image_setregion(reg)

Description

A region description is sent to the imager (ds9 by default), where it is drawn in the current frame. There is no return value.

  • reg - region description in CIAO region syntax

Example

sherpa> reg = "circle(4300,3710,15)"
sherpa> image_setregion(reg)

If "reg" is a string defining a region in CIAO region syntax, then the region is drawn in the current frame of ds9. In this example, a circular region with center coordinates (4300, 3710) and radius=15 is drawn.
