MultibandExposure class This class acts as a container for multiple `afw.Exposure` objects. All exposures must have the same bounding box, and the associated images must all have the same data type. See `MultibandTripleBase` for parameter definitions.

Get a multiband PSF image The PSF Kernel Image is computed for each band and combined into a (filter, y, x) array and stored as `self._psfImage`. The result is not cached, so if the same PSF is expected to be used multiple times it is a good idea to store the result in another variable. Parameters ---------- position: `Point2D` or `tuple` Coordinates to evaluate the PSF. If `position` is `None` then `Psf.getAveragePosition()` is used. Returns ------- self._psfImage: array The multiband PSF image.

Load a multiband exposure from a butler Because each band is stored in a separate exposure file, this method can be used to load all of the exposures for a given set of bands Parameters ---------- butler: `lsst.daf.butler.Butler` Butler connection to use to load the single band calibrated images bands: `list` or `str` List of names for each band args: `list` Arguments to the Butler. kwargs: `dict` Keyword arguments to pass to the Butler that are the same in all bands. Returns ------- result: `MultibandExposure` The new `MultibandExposure` created by combining all of the single band exposures.
