Detailed Description

Stack bright stars together to build an extended PSF model.

Definition at line 364 of file extended_psf.py.

Member Function Documentation

_set_up_stacking()

lsst.pipe.tasks.extended_psf.StackBrightStarsTask._set_up_stacking ( self, example_stamp )

protected

Configure stacking statistic and control from config fields.

Definition at line 370 of file extended_psf.py.

removeInvalidStamps()

lsst.pipe.tasks.extended_psf.StackBrightStarsTask.removeInvalidStamps	(		self,
			read_stars )

Remove stamps that do not have enough valid pixels in the annulus.

Parameters
----------
read_stars : `list` of `lsst.pipe.tasks.processBrightStars.BrightStarStamp`
    List of bright star stamps to be stacked.

Definition at line 384 of file extended_psf.py.

run()

lsst.pipe.tasks.extended_psf.StackBrightStarsTask.run	(		self,
			bss_ref_list,
			stars_dict,
			region_name = None )

Read input bright star stamps and stack them together.

The stacking is done iteratively over smaller areas of the final model
image to allow for a great number of bright star stamps to be used.

Parameters
----------
bss_ref_list : `list` of
        `lsst.daf.butler._deferredDatasetHandle.DeferredDatasetHandle`
    List of available bright star stamps data references.
stars_dict: `dict`
    Dictionary to store the number of stars used to generate the PSF.
region_name : `str`, optional
    Name of the focal plane region, if applicable. Only used for
    logging purposes, when running over multiple such regions
    (typically from `MeasureExtendedPsfTask`)
