Paul Price added a comment - 15/Nov/16 8:46 PM This was a LOT more work than I was expecting because, in addition to adding a configuration file, it also required: adapting meas_extensions_convolved to work with forced measurement (I changed it to wrap a base class, similar to how C++ plugins work; Jim Bosch may be interested in adapting the wrapper into meas_base for general use). adapting meas_base to do undeblended measurement in the ForcedMeasurementTask as well as the SingleFrameMeasurementTask . changing meas_extensions_photometryKron to make the source of the Kron radius (for forced measurement) configurable (because there's no undeblended_ext_photometryKron_KronFlux_radius column in the reference). Lauren MacArthur , would you mind having a look at these, please? If you feel it's a bit much, we can split it up. price@price-laptop:~/LSST/obs/subaru (tickets/DM-7889=) $ git sub commit 0e9fb31f1d7ae0a4ab85401a6c9c979b3364cbcc Author: Paul Price <price@astro.princeton.edu> Date: Fri Nov 4 14:17:45 2016 -0400   activate measurements used in s16a production afterburner The HSC s16a production's afterburner included two measurements features which have been ported to LSST: measurement on the undeblended image (to allow potentially useful measurements where the deblender fails, and to compare with software that doesn't use a deblender), and measurement of convolved fluxes (to provide fluxes in multiple bands with a common seeing, e.g., for photometric redshifts). This patch activates these features for HSC and Suprime-Cam.   config/convolvedFluxes.py | 9 +++++++++ config/forcedPhotCoadd.py | 27 +++++++++++++++++++++++++++ config/measureCoaddSources.py | 1 + config/processCcd.py | 6 ++++++ 4 files changed, 43 insertions(+)     price@price-laptop:~/LSST/meas/extensions/convolved (tickets/DM-7889=) $ git subcommit 5c904dca6e5f32c4c3a3f1b31e4e5afa44a42a43 Author: Paul Price <price@astro.princeton.edu> Date: Mon Nov 7 20:49:48 2016 -0600   wrap ConvolvedFluxPlugin to allow use in forced measurement Change the ConvolvedFluxPlugin class into a base class that we then wrap with the appropriate plugin base class. There's also a little bit of fiddling required to give the forced measurement a slightly different signature. In order to do the forced measurement, we need to add transformation from the reference frame to the measurement frame. Since we're already doing forced measurement (center is provided, aperture shape and radius are provided), moved the calculation into a 'measureForced' method, and have 'measure' call that with a null transformation. Modified the test to check that forced measurement also works.   python/lsst/meas/extensions/convolved/convolved.py | 203 ++++++++++++++------- tests/test_convolved.py | 76 ++++++-- 2 files changed, 201 insertions(+), 78 deletions(-)     price@price-laptop:~/LSST/meas/base (tickets/DM-7889=) $ git sub commit 7d67323726849bf986d3c0a7261dbdd8e32e2c94 Author: Paul Price <price@astro.princeton.edu> Date: Mon Nov 7 20:47:05 2016 -0600   refactor undeblended measurement into BaseMeasurementTask This makes it available in the ForcedMeasurementTask as well as SingleFrameMeasurementTask.

Paul Price added a comment - 19/Dec/16 3:53 PM Thanks David Reiss . I've addressed the two small comments on meas_base, rebased everything against origin/master , and am in the process of doing a final Jenkins run before merging.

Paul Price added a comment - 19/Dec/16 7:42 PM Jenkins passed . Merged to master.
