WCSMatch

WCSMatch is a global plugin for the Ginga image viewer that allows you to roughly align images with different scales and orientations using the images’ World Coordinate System (WCS) for viewing purposes.

Plugin Type: Global

WCSMatch is a global plugin. Only one instance can be opened.

Usage

To use, simply start the plugin, and from the plugin GUI select a channel from the drop-down menu labeled “Reference Channel”. The image contained in that channel will be used as a reference for zooming and orienting the images in the other channels.

The channels will be synchronized in viewing (zoom, pan, rotate, and transform). To “unlock” the synchronization, simply select “None” from the “Reference Channel” drop-down menu.

Currently, there is no way to limit the channels that are affected by the plugin.
