22 r"""Base classes for forced measurement plugins and the driver task for these.
23 
24 In forced measurement, a reference catalog is used to define restricted
25 measurements (usually just fluxes) on an image. As the reference catalog may
26 be deeper than the detection limit of the measurement image, we do not assume
27 that we can use detection and deblend information from the measurement image.
28 Instead, we assume this information is present in the reference catalog and
29 can be "transformed" in some sense to the measurement frame. At the very
30 least, this means that `~lsst.afw.detection.Footprint`\ s from the reference
31 catalog should be transformed and installed as Footprints in the output
32 measurement catalog. If we have a procedure that can transform "heavy"
33 Footprints (ie, including pixel data), we can then proceed with measurement as
34 usual, but using the reference catalog's ``id`` and ``parent`` fields to
35 define deblend families. If this transformation does not preserve
36 heavy Footprints (this is currently the case, at least for CCD forced
37 photometry), then we will only be able to replace objects with noise one
38 deblend family at a time, and hence measurements run in single-object mode may
39 be contaminated by neighbors when run on objects with ``parent != 0``.
40 
41 Measurements are generally recorded in the coordinate system of the image
42 being measured (and all slot-eligible fields must be), but non-slot fields may
43 be recorded in other coordinate systems if necessary to avoid information loss
44 (this should, of course, be indicated in the field documentation). Note that
45 the reference catalog may be in a different coordinate system; it is the
46 responsibility of plugins to transform the data they need themselves, using
47 the reference WCS provided. However, for plugins that only require a position
48 or shape, they may simply use output `~lsst.afw.table.SourceCatalog`\'s
49 centroid or shape slots, which will generally be set to the transformed
50 position of the reference object before any other plugins are run, and hence
51 avoid using the reference catalog at all.
52 
53 Command-line driver tasks for forced measurement include
54 `ForcedPhotImageTask`, `ForcedPhotCcdTask`, and `ForcedPhotCoaddTask`.

295 
296  - `generateMeasCat` must be called to create the output ``measCat``
297  argument.
298  - `~lsst.afw.detection.Footprint`\ s appropriate for the forced sources
299  must be attached to the ``measCat`` records. The
300  `attachTransformedFootprints` method can be used to do this, but
301  this degrades "heavy" (i.e., including pixel values)
302  `~lsst.afw.detection.Footprint`\s to regular
303  `~lsst.afw.detection.Footprint`\s, leading to non-deblended
304  measurement, so most callers should provide
305  `~lsst.afw.detection.Footprint`\s some other way. Typically, calling
306  code will have access to information that will allow them to provide
307  heavy footprints - for instance, `ForcedPhotCoaddTask` uses the
308  heavy footprints from deblending run in the same band just before
309  non-forced is run measurement in that band.
