lsst.meas.extensions.shapeHSM

The lsst.meas.extensions.shapeHSM module provides algorithms for HSM shape measurement. The algorithm was initially described in Hirata & Seljak (2003), and was modified later in Mandelbaum et al. (2005). HSM is named after the primary authors: Christopher Hirata, Uros Seljak, and Rachel Mandelbaum. Their implementation of this algorithm lives within GalSim, and this package interacts with the Python layer of GalSim to make the measurements.
