Addition of several images improves the signal to noise ratio.
This procedure is useful especially for processing of
AIA 93Å, 131Å, 335 Å images.

A single AIA 335 Å (left) and sum of 5 images (right)
|
- Open the first image.
- Add the second and following images by Add button.
- The number of images is not limited but the dynamic range of images sum is 16 bits/pixel
i.e. addition of too many images may cause saturation.
