      Description

      Based on a discussion in the Tea Time HipChat room today, this is a "note to ourselves" to take a look at the behavior of Firefly when visualizing images with negative flux values.

      This is important for difference imaging and is therefore highly relevant to both LSST and ZTF (if ZTF difference images become visible through Firefly at some point).

      The behavior of the asinh stretch, in particular, should be looked at.
