While I am trying to create a Dark Library with XSIF files, automatically switches to FITS. In the meantime in the Capture module, I can capture darks as XSIF with no issue.

@nou informed me that the Dark Library requests only FITS files. I believe now with the XSIF support, we will extend it there too.

In the meantime, does that mean we need to shoot FITS only if we want to use the Dark Library? Does the MasteDark.FITS works correctly with Lights001.XSIF?
