Major Functionality and Interface Changes
Improved semantics for loading
MaskedImages from arbitrary FITS files
Multi-band processing for coadds
See the description of the multi-band coadd processing work performed in S15 for details. In short, four new command-line Tasks have been added for consistent multi-band coadd processing:
It is now possible to use
lsst.afw.cameraGeom.utils to display CCD data laid out in the focal plane. An example of how this functionality works in practice is available as an IPython notebook. (DM-2347)
The following fixes resolve problems visible to end users.
DipoleMeasurementConfig.setDefaults method incorrectly contained a
return that was executed before the defaults were actually applied. This has been corrected, and a number of tests updated to rely on those defaults. (DM-3159)
Build and code improvements
These improvements should not usually be visible to end users. They may be important for developers, however.
Several performance optimizations to the (C++) algorithms used in the deblender have been implemented, in particular those which identify objects with significant amounts of their flux attributed to edge pixels. In addition, memory usage was reduced by removing unused mask planes left over from debugging, not storing masks for deblending templates, and by clipping template images when their associated
Footprints are clipped. (DM-2914)
Release notes for Qserv and Webserv
These release notes focus on the Science Pipelines part of the LSST Stack, but there are other important components developed by Data Management teams.
