Function Documentation

dictToTuple()

def lsst.pipe.drivers.constructCalibs.dictToTuple	(		dict_,
			keys
	)

Return a tuple of specific values from a dict.

This provides a hashable representation of the dict from certain keywords. This can be useful for creating e.g., a tuple of the values in the DataId that identify the CCD.

Parameters

dict_	dict to parse
keys	keys to extract (order is important)

Returns

tuple of values

getCcdIdListFromExposures()

def lsst.pipe.drivers.constructCalibs.getCcdIdListFromExposures	(		expRefList,
			level = "sensor",
			ccdKeys = ["ccd"]
	)

Determine a list of CCDs from exposure references.

This essentially inverts the exposure-level references (which provides a list of CCDs for each exposure), by providing a dataId list for each CCD. Consider an input list of exposures [e1, e2, e3], and each exposure has CCDs c1 and c2. Then this function returns:

{(c1,): [e1c1, e2c1, e3c1], (c2,): [e1c2, e2c2, e3c2]}

This is a dict whose keys are tuples of the identifying values of a CCD (usually just the CCD number) and the values are lists of dataIds for that CCD in each exposure. A missing dataId is given the value None.

Parameters

expRefList	List of data references for exposures
level	Level for the butler to generate CCDs
ccdKeys	DataId keywords that identify a CCD

Returns

dict of data identifier lists for each CCD; keys are values of ccdKeys in order

getSize()

def lsst.pipe.drivers.constructCalibs.getSize

(

dimList

)

Determine a consistent size, given a list of image sizes

mapToMatrix()

def lsst.pipe.drivers.constructCalibs.mapToMatrix	(		pool,
			func,
			ccdIdLists,
			args,
			kwargs
	)

Generate a matrix of results using pool.map

The function should have the call signature:
    func(cache, dataId, *args, **kwargs)

We return a dict mapping 'ccd name' to a list of values for
each exposure.

@param pool  Process pool
@param func  Function to call for each dataId
@param ccdIdLists  Dict of data identifier lists for each CCD name
@return matrix of results
