I keep getting black specs in my bright stars after drizzle integration. They go away when i uncheck "enable pixel rejection" but then i get loads of artifacts in my image. My initial image and drizzle data is generated through WBP and my non drizzled images are all okay with no specs or artifacts. I have tried many different things but nothing seems to help. Can anyone give my and idea where i am going wrong

Cheers

Hi Andy,
check the Pixel rejection algorithm in the ImageIntegration process. I have seen those black pixel when using Percentile Clipping as rejection algorithm together with LocalNormalization as normalization method. They disappeared after I used Winsorized Sigma Clippping.

Thanks for the reply. I did manage to sort out the issue. Cant remember what i did now. One of the rejection settings in image integration..
