      Description

      Three significant changes were made to CModel in HSC-1339. They were described by Jim Bosch in a post to hsc_software. They include:

      • Changing the method by which the initial approximation is determined;
      • Changing the determination of the pixel region to use in fitting;
      • A new prior on ellipticity and radius.

      Please port these changes to LSST.

      Also include the results of fixing the bug described in HSC-1384.
