◆ addExposures()

lsst.meas.algorithms.detection.addExposures ( exposureList)
Add a set of exposures together.

Parameters
----------
exposureList : `list` of `lsst.afw.image.Exposure`
    Sequence of exposures to add.

Returns
-------
addedExposure : `lsst.afw.image.Exposure`
    An exposure of the same size as each exposure in ``exposureList``,
    with the metadata from ``exposureList[0]`` and a masked image equal
    to the sum of all the exposure's masked images.
