applyAltMaskPlanes()

def lsst.pipe.tasks.assembleCoadd.applyAltMaskPlanes	(		self,
			mask,

Apply in place alt mask formatted as SpanSets to a mask.

Parameters
----------
mask : `lsst.afw.image.Mask`
    Original mask.
altMaskSpans : `dict`
    SpanSet lists to apply. Each element contains the new mask
    plane name (e.g. "CLIPPED and/or "NO_DATA") as the key,
    and list of SpanSets to apply to the mask.

Returns
-------
mask : `lsst.afw.image.Mask`
    Updated mask.

Assemble the coadd for a sub-region.

For each coaddTempExp, check for (and swap in) an alternative mask
if one is passed. Remove mask planes listed in
`config.removeMaskPlanes`. Finally, stack the actual exposures using
`lsst.afw.math.statisticsStack` with the statistic specified by
statsFlags. Typically, the statsFlag will be one of lsst.afw.math.MEAN for
a mean-stack or `lsst.afw.math.MEANCLIP` for outlier rejection using
an N-sigma clipped mean where N and iterations are specified by
statsCtrl.  Assign the stacked subregion back to the coadd.

Parameters
----------

    The target exposure for the coadd.
bbox : `lsst.geom.Box`
    Sub-region to coadd.
tempExpRefList : `list`
    List of data reference to tempExp.
imageScalerList : `list`
    List of image scalers.
weightList : `list`
    List of weights.
altMaskList : `list`
    List of alternate masks to use rather than those stored with
    tempExp, or None.  Each element is dict with keys = mask plane
    name to which to add the spans.
statsFlags : `lsst.afw.math.Property`
    Property object for statistic for coadd.
statsCtrl : `lsst.afw.math.StatisticsControl`
    Statistics control object for coadd.
nImage : `lsst.afw.image.ImageU`, optional
    Keeps track of exposure count for each pixel.

Assemble a coadd from input warps

Assemble the coadd using the provided list of coaddTempExps. Since
the full coadd covers a patch (a large area), the assembly is
performed over small areas on the image at a time in order to
conserve memory usage. Iterate over subregions within the outer
bbox of the patch using `assembleSubregion` to stack the corresponding
subregions from the coaddTempExps with the statistic specified.
Set the edge bits the coadd mask based on the weight map.

Parameters
----------
skyInfo : `lsst.pipe.base.Struct`
    Struct with geometric information about the patch.
tempExpRefList : `list`
    List of data references to Warps (previously called CoaddTempExps).
imageScalerList : `list`
    List of image scalers.
weightList : `list`
    List of weights
altMaskList : `list`, optional
    List of alternate masks to use rather than those stored with
    tempExp.
mask : `int`, optional
    Bit mask value to exclude from coaddition.
supplementaryData : lsst.pipe.base.Struct, optional
    Struct with additional data products needed to assemble coadd.
    Only used by subclasses that implement `makeSupplementaryData`
    and override `run`.

Returns
-------
result : `lsst.pipe.base.Struct`
   Result struct with components:

   - ``coaddExposure``: coadded exposure (``lsst.afw.image.Exposure``).
   - ``nImage``: exposure count image (``lsst.afw.image.Image``), if requested.
   - ``warpRefList``: input list of refs to the warps (
