Description
I don't know what the underlying performance issue is, but wow it is slow (clipping a stack of 25 4k x 4k images takes minutes).
Contributor guide
Research direction
Start by locating the sigma-clipping entry point used by ccdproc and measuring it on a stack of 25 4k x 4k images. The issue does not name a file or test, or identify the cause; done means the workload clips substantially faster.
