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: `Butler` Butler connection to use to load the single band calibrated images filters: `list` or `str` List of filter names for each band filterKwargs: `dict` Keyword arguments to pass to the Butler that are different for each filter. The keys are the names of the arguments and the values should also be dictionaries, with filter names as keys and the value of the argument for the given filter as values. 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.

Shift the bounding box but keep the same Extent This is different than `MultibandBase.setXY0` because the multiband `image`, `mask`, and `variance` objects must all have their bounding boxes updated. Parameters ---------- xy0 : `Point2I` New minimum bounds of the bounding box

Shift a bounding box by an offset, but keep the same Extent This method is broken until DM-10781 is completed. Parameters ---------- offset: `Extent2I` Amount to shift the bounding box in x and y. Returns ------- result: `MultibandBase` A copy of the object, shifted by `offset`
