The all corrected (FR) JPEG files from years 1997 to 2000 do not have the same pixel size. Their image sizes vary from 1835 X 1835 to 2032 X 2032.
The images from July 2000 onwards which have been analyzed by the AAFDCC code have a resolution of 2032 X 2032 pixels. So, all the JPEG images were rescaled to meet the required pixel size of 2032 X 2032.
A simple terminal command can resize all images to 2032 X 2032:
convert <filename> -resize 2032x2032 <newfilename>
Example:
 |
| Original 1835 X 1835 image |
 |
| Resized 2032 X 2032 image |
 |
| A Solar filament in the original image |
 |
| The same Solar filament in the resized image |
