Align by WCS
The Align by WCS command uses the world
coordinate information stored in the image headers to align images
to sub pixel precision. This command works with an image set.
Alternatively, if no WCS calibration exists, or for general
purposes, you can also align images using the
Image Registration command.
Note: This command may not give accurate subpixel
alignment for images where the alignment involves higher order
coefficients that are saved to the headers using non-standard
keywords.
Procedure
-
Load the target images as an
image set in a single Image Window.
-
Bring to the top of the window stack the image
to which the others will be registered.
-
Use the Align by WCS command to align all
the images to the reference image. The alignment can be removed by
using the
Undo command.
You can also view all of the WCS related keyword
data by using the
List WCS Keywords command.
