- This is a hotfix to fix gFind: I believe there was an indent error when setting the `output` variable, and there was also no update in the case where the band was missing entirely.  gFind will now set a given band's `exptime` dict key to 0., and the `to` and `t1` keys to None, if the band has no exposure time in the database.  This should support using gFind as imports in a script.
