| Title: |
Improvement of SXT Image Alignment in Order to Obtain High-Resolution Temperature Maps |
|
| Authors: | M. Siarkowski, J. Sylwester, J. Jakimiec and M. Tomczak | |
| Abstract: | Examples
are shown and discussed which indicate that published temperature maps
derived using SXT intensity ratio technique may be substantially biased
if standard image processing routines are used to coalign the images.
Methods are discussed which allow for independent of the Yohkoh satellite
pointing information, precise (0.12 arcsec), alignment of images obtained
in selected energy bands (filters). Examples are presented illustrating
the differences in the temperature maps derived using standard and additional
pointing correction (APC).
