Count the number of input images which contributed to a a source.
Parameters
----------
config : `InputCountConfig`
Plugin configuraion.
name : `str`
Plugin name.
schema : `lsst.afw.table.Schema`
The schema for the measurement output catalog. New fields will be
added to hold measurements produced by this plugin.
metadata : `lsst.daf.base.PropertySet`
Plugin metadata that will be attached to the output catalog
Notes
-----
Information is derived from the image's `~lsst.afw.image.CoaddInputs`.
Note these limitation:
- This records the number of images which contributed to the pixel in the
center of the source footprint, rather than to any or all pixels in the
source.
- Clipping in the coadd is not taken into account.

| def lsst.meas.base.plugins.InputCountPlugin.fail | ( | self, | |
| measRecord, | |||
error = None |
|||
| ) |
Record a measurement failure.
This default implementation simply records the failure in the source
record.
Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
Catalog record for the source being measured.
error : `Exception`
Error causing failure, or `None`.

| def lsst.meas.base.plugins.InputCountPlugin.getExecutionOrder | ( | cls | ) |
Get the relative execution order of this plugin. Must be reimplemented as a class method by concrete derived classes.

| def lsst.meas.base.plugins.InputCountPlugin.measure | ( | self, | |
| measRecord, | |||
| exposure, | |||
| center | |||
| ) |
Measure a single source.
It is the responsibility of this method to perform the desired
measurement and record the result in the `measRecord`.
Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
Catalog record for the source being measured.
exposure : `lsst.afw.image.Exposure`
Exposure on which the source is being measured.
center : `lsst.geom.Point2D`
Pixel coordinates of the object.
Raises
------
MeasurementError
Raised if the measurement fails for a known/justifiable reason.
