      Description

      lsst::afw::geom::SkyWcs presently has no reliable way to extract SIP terms, and that will likely be true for several more months. However, one can easily get a TAN approximation centered at any point. Is that good enough to initialize jointcal?

      Please run jointcal on a moderate size dataset with significant distortion and see if it can reliably produce a good model if the initial WCS has hasDistortion false.
