__init__()

			reuse = tuple(),
			kwargs
	)

batchWallTime()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.batchWallTime	(		cls,
			time,
			parsedCmd,
			numCores
	)

Return walltime request for batch job.

Parameters

time	Requested time per iteration
parsedCmd	Results of argument parsing
numCores	Number of cores

Returns

float walltime request length

Definition at line 120 of file coaddDriver.py.

checkTract()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.checkTract	(		self,
			cache,
			tractId,
			selectIdList
	)

Check whether a tract has any overlapping inputs.

This method only runs on slave nodes.

Parameters

cache	Pool cache
tractId	Data identifier for tract
selectDataList	List of selection data

Returns

whether tract has any overlapping inputs

Definition at line 219 of file coaddDriver.py.

coadd()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.coadd	(		self,
			cache,
			data
	)

Construct coadd for a patch and measure.

Only slave nodes execute this method.

Because only one argument may be passed, it is expected to contain multiple elements, which are:

Parameters

patchRef	data reference for patch
selectDataList	List of SelectStruct for inputs

Definition at line 265 of file coaddDriver.py.

readSelection()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.readSelection	(		self,
			cache,
			selectId
	)

Read Wcs of selected inputs.

This method only runs on slave nodes. This method is similar to SelectDataIdContainer.makeDataRefList, creating a Struct like a SelectStruct, except with a dataId instead of a dataRef (to ease MPI).

Parameters

cache	Pool cache
selectId	Data identifier for selected input

Returns

a SelectStruct with a dataId instead of dataRef

Definition at line 196 of file coaddDriver.py.

run()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.run	(		self,
			patchRefList,
			butler,
			selectDataList = []
	)

Run stacking on a tract.

This method only runs on the master node.

Parameters

patchRefList	List of patch data references for tract
butler	Data butler
selectDataList	List of SelectStruct for inputs

Definition at line 169 of file coaddDriver.py.

runDataRef()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.runDataRef	(		self,
			tractPatchRefList,
			butler,
			selectIdList = []
	)

Determine which tracts are non-empty before processing.

Parameters

tractPatchRefList	List of tracts and patches to include in the coaddition
butler	butler reference object
selectIdList	List of data Ids (i.e. visit, ccd) to consider when making the coadd

Returns

list of references to sel.runTract function evaluation for each tractPatchRefList member

Definition at line 133 of file coaddDriver.py.

selectExposures()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.selectExposures	(		self,
			patchRef,
			selectDataList
	)

Select exposures to operate upon, via the SelectImagesTask.

This is very similar to CoaddBaseTask.selectExposures, except we return a list of SelectStruct (same as the input), so we can plug the results into future uses of SelectImagesTask.

Parameters

patchRef	data reference to a particular patch
selectDataList	list of references to specific data products (i.e. visit, ccd)

Returns

filtered list of SelectStruct

Definition at line 327 of file coaddDriver.py.

warp()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.warp	(		self,
			cache,
			patchId,
			selectDataList
	)

Warp all images for a patch.

Only slave nodes execute this method.

Because only one argument may be passed, it is expected to contain multiple elements, which are:

Parameters

patchRef	data reference for patch
selectDataList	List of SelectStruct for inputs

Returns

selectDataList with non-overlapping elements removed

Definition at line 247 of file coaddDriver.py.

writeMetadata()

def lsst.pipe.drivers.coaddDriver.CoaddDriverTask.writeMetadata	(		self,
			dataRef
	)

Definition at line 354 of file coaddDriver.py.
