| Abstract: |
We have developed a set of tasks in the IRAF environment for registering, matching the point-spread functions, and matching the intensity scales of two or more images. This software can be applied to a wide variety of astronomical problems including searches for transient events such as extragalactic novae and supernovae, continuum-subtraction for emission line imaging, and the examination of small scale color gradients. We briefly describe the algorithms and illustrate the software with images obtained under different seeing conditions. |
