      Description

      This issue involves transferring changesets from the following HSC issues:

      • HSC-145 Investigate approximating rather than interpolating backgrounds
      • HSC-1047 Background object cannot be loaded with butler
      • HSC-1213 Set background 'approximate' control settings when background control is created.
      • HSC-1221 tests failing in ip_diffim
      • HSC-1217 Verify backgroundList IO works properly when Approximate is enabled in background control - HSC JIRA

      The Approximate (Chebyshev) approach greatly improves the background subtraction around bright objects compared with the interpolation scheme currently in use (which over-subtracts near bright objects).
