Member Function Documentation

◆ _add_snaps()

lsst.pipe.tasks.snapCombine.SnapCombineTask._add_snaps	(	self,
		snap0,
		snap1 )

protected

    Snap exposure 1.

Returns
-------
combined : `lsst.afw.image.Exposure`
    Combined exposure.

◆ _merge_visit_info()

lsst.pipe.tasks.snapCombine.SnapCombineTask._merge_visit_info	(	self,
		info0,
		info1 )

protected

Merge the visitInfo values from the two exposures.

In particular:
 * id will be the id of snap 0.
 * date will be the average of the dates.
 * exposure time will be the sum of the times.

Parameters
----------
info0, info1 : `lsst.afw.image.VisitInfo`

Parameters
----------
snap0, snap1 : `lsst.afw.image.Exposure`
    Exposures to combine.

Returns
-------
result : `lsst.pipe.base.Struct`
    Results as a struct with attributes:

    ``exposure``
        Snap-combined exposure.

Definition at line 90 of file snapCombine.py.

◆ run()

lsst.pipe.tasks.snapCombine.SnapCombineTask.run	(		self,
			exposures )

Combine one or two snaps, returning the combined image.

Parameters
----------
exposures : `lsst.afw.image.Exposure` or `list` [`lsst.afw.image.Exposure`]
