Doug,

ATWT is the AtrousWaveletTransform (you can see why the name gets abbreviated!) It's wavelet based so it allows you operate at different physical scales. You can use it to do noise reduction, even on linear images. It also does sharpening.

You are right. It's surprising that the PixInsight web site doesn't reference the reference guide even if it's not official.

BTW, I thought FFS might have been a Fast Fourier Transform minus one?

Cheers,
Rick.
