Bit-depth is 32-bit. I was trying an integration on a set of photo’s, in which PI substracted the comet. These photo’s were already registered and normalized in APP prior to PI processing. In App I then switched off registration and tried integrating with LNC 1, Windsor Sigma Clipping at 1.0 and 3 iterations. I was just trying some rather extreme settings as I want to get rid of as much background as possible to try and combine the comet and stars later.
