str | _DefaultName = "measurement" |
Ultimate base class for all measurement tasks. Parameters ---------- algMetadata : `lsst.daf.base.PropertyList` or `None` Will be modified in-place to contain metadata about the plugins being run. If `None`, an empty `~lsst.daf.base.PropertyList` will be created. **kwds Additional arguments passed to `lsst.pipe.base.Task.__init__`. Notes ----- This base class for `SingleFrameMeasurementTask` and `ForcedMeasurementTask` mostly exists to share code between the two, and generally should not be used directly.

lsst.meas.base.baseMeasurement.BaseMeasurementTask.callMeasure | ( | self, | |
measRecord, | |||
* | args, | ||
** | kwds ) |
Call ``measure`` on all plugins and consistently handle exceptions. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` The record corresponding to the object being measured. Will be updated in-place with the results of measurement. *args Positional arguments forwarded to ``plugin.measure`` **kwds Keyword arguments. Two are handled locally: beginOrder : `int` Beginning execution order (inclusive). Measurements with ``executionOrder`` < ``beginOrder`` are not executed. `None` for no limit. endOrder : `int` Ending execution order (exclusive). Measurements with ``executionOrder`` >= ``endOrder`` are not executed. `None` for no limit. Others are forwarded to ``plugin.measure()``. Notes ----- This method can be used with plugins that have different signatures; the only requirement is that ``measRecord`` be the first argument. Subsequent positional arguments and keyword arguments are forwarded directly to the plugin. This method should be considered "protected": it is intended for use by derived classes, not users.

lsst.meas.base.baseMeasurement.BaseMeasurementTask.callMeasureN | ( | self, | |
measCat, | |||
* | args, | ||
** | kwds ) |
Call ``measureN`` on all plugins and consistently handle exceptions. Parameters ---------- measCat : `lsst.afw.table.SourceCatalog` Catalog containing only the records for the source family to be measured, and where outputs should be written. *args Positional arguments forwarded to ``plugin.measure()`` **kwds Keyword arguments. Two are handled locally: beginOrder: Beginning execution order (inclusive): Measurements with ``executionOrder`` < ``beginOrder`` are not executed. `None` for no limit. endOrder: Ending execution order (exclusive): measurements with ``executionOrder`` >= ``endOrder`` are not executed. `None` for no ``limit``. Others are are forwarded to ``plugin.measure()``. Notes ----- This method can be used with plugins that have different signatures; the only requirement is that ``measRecord`` be the first argument. Subsequent positional arguments and keyword arguments are forwarded directly to the plugin. This method should be considered "protected": it is intended for use by derived classes, not users.

lsst.meas.base.baseMeasurement.BaseMeasurementTask.doMeasurement | ( | self, | |
plugin, | |||
measRecord, | |||
* | args, | ||
** | kwds ) |
Call ``measure`` on the specified plugin. Exceptions are handled in a consistent way. Parameters ---------- plugin : subclass of `BasePlugin` Plugin that will be executed. measRecord : `lsst.afw.table.SourceRecord` The record corresponding to the object being measured. Will be updated in-place with the results of measurement. *args Positional arguments forwarded to ``plugin.measure()``. **kwds Keyword arguments forwarded to ``plugin.measure()``. Notes ----- This method can be used with plugins that have different signatures; the only requirement is that ``plugin`` and ``measRecord`` be the first two arguments. Subsequent positional arguments and keyword arguments are forwarded directly to the plugin. This method should be considered "protected": it is intended for use by derived classes, not users.

lsst.meas.base.baseMeasurement.BaseMeasurementTask.doMeasurementN | ( | self, | |
plugin, | |||
measCat, | |||
* | args, | ||
** | kwds ) |
Call ``measureN`` on the specified plugin. Exceptions are handled in a consistent way. Parameters ---------- plugin : subclass of `BasePlugin` Plugin that will be executed. measCat : `lsst.afw.table.SourceCatalog` Catalog containing only the records for the source family to be measured, and where outputs should be written. *args Positional arguments forwarded to ``plugin.measureN()``. **kwds Keyword arguments forwarded to ``plugin.measureN()``. Notes ----- This method can be used with plugins that have different signatures; the only requirement is that the ``plugin`` and ``measCat`` be the first two arguments. Subsequent positional arguments and keyword arguments are forwarded directly to the plugin. This method should be considered "protected": it is intended for use by derived classes, not users.

Get a set of footprints from a catalog, keyed by id. Parameters ---------- catalog : `lsst.afw.table.SourceCatalog` Catalog with `lsst.afw.detection.Footprint`s attached. Returns ------- footprints : `dict` [`int`: (`int`, `lsst.afw.detection.Footprint`)] Dictionary of footprint, keyed by id number, with a tuple of the parent id and footprint.

lsst.meas.base.baseMeasurement.BaseMeasurementTask.initializePlugins | ( | self, | |
** | kwds ) |
Initialize plugins (and slots) according to configuration. Parameters ---------- **kwds Keyword arguments forwarded directly to plugin constructors. Notes ----- Derived class constructors should call this method to fill the `plugins` attribute and add corresponding output fields and slot aliases to the output schema. In addition to the attributes added by `BaseMeasurementTask.__init__`, a ``schema``` attribute holding the output schema must be present before this method is called. Keyword arguments are forwarded directly to plugin constructors, allowing derived classes to use plugins with different signatures.
