Description

Implement diagnostics that reflect the goodness of fit of the spatial kernel model (k_s) to the originally derived kernels (k). These are

  • Autocorrelation in residuals : [ (k - k_s) * (k - k_s) ] (r)
  • Data-residual cross correlation : [ k * (k - k_s) + (k - k_s) * k ] (r)

Andy:

As per discussion at the 22 March 2011 DC3 meeting, the currently unused ip_diffim is being removed from the scheduled buildbot trunk Vs trunk runs. This move was taken since the afw reorg will probably cause the old ip_diffim to fail and there is little incentive to repair a version being replaced by a total rewrite.

Notify Robyn when the replacement version of ip_diffim is installed and ready for testing.

Not clear that the autocorrelation results are useful. However, this ticket has been merged back to trunk since it includes changes from tickets #1176, and also resolves ticket #1626. A new ticket needs to be filed to get the documentation up to date.
