meas_extensions_shapeHSM wraps the HSM shape measurement algorithms in GalSim for use by our measurement framework. It is probably the premier shape measurement package working with our stack at the moment. We are using it in HSC as the principal source of our shape measurements for early science. I propose including it in lsst_distrib so it may easily be built, used and CI-ed.
meas_extensions_shapeHSM depends on GalSim, which in turn depends on TMV. Both of these have already been packaged for use in LSST.
Implementation will be on
