CrosstalkFilterTask#

class lsst.cp.pipe.CrosstalkFilterTask(*, config: PipelineTaskConfig | None = None, log: logging.Logger | LsstLogAdapter | None = None, initInputs: dict[str, Any] | None = None, **kwargs: Any)#

Bases: PipelineTask

Task to compare crosstalk solutions between detectors, to identify and remove outliers.

Methods Summary

`find_outliers`(matrix0, matrix1)	Do checks to see if an element of the matrix is out-of-family.
`replace_outliers`(matrix0, matrix1, isBad, ...)	Do checks to see if an element of the matrix is out-of-family.
`run`(inputCrosstalk, camera, inputDims, ...)	Compare crosstalk solutions to produce filtered crosstalk calibrations.
`runQuantum`(butlerQC, inputRefs, outputRefs)	Ensure that the input and output dimensions are passed along.

Methods Documentation

find_outliers(matrix0, matrix1)#

Do checks to see if an element of the matrix is out-of-family.

Parameters#

matrix0np.ndarray, (Ndet, Namp, Namp): Matrix holding the 0th-order terms.
matrix1np.ndarray, (Ndet, Namp, Namp): Matrix holding the 1st-order terms.

Returns#

resultslsst.pipe.base.Struct

Results struct containing

median0: Median in-family value (np.ndarray (Namp, Namp)).
stdev0: MAD effective sigma in-family value (np.ndarray (Namp, Namp)).
median1: Median in-family value (np.ndarray (Namp, Namp)).
stdev1: MAD effective sigma in-family value (np.ndarray (Namp, Namp)).
isBad: Boolean indicator that an element has been replaced (np.ndarray (Ndet, Namp, Namp)).

Raises#

ValueError :: Raised if the inputs have a mismatch in size.

replace_outliers(matrix0, matrix1, isBad, median0, median1)#

Do checks to see if an element of the matrix is out-of-family.

Parameters#

matrix0np.ndarray, (Ndet, Namp, Namp): Matrix holding the 0th-order terms.
matrix1np.ndarray, (Ndet, Namp, Namp): Matrix holding the 1st-order terms.
isBadnp.ndarray, (Ndet, Namp, Namp): Matrix holding the boolean “is bad”.
median0np.ndarray, (Namp, Namp): Matrix of median 0th-order terms.
median1np.ndarray, (Namp, Namp): Matrix of median 1st-order terms.

Returns#

resultslsst.pipe.base.Struct

Results struct containing

new_matrix0: Replacement matrix0, with median substitutions. (np.ndarray (Ndet, Namp, Namp)).
new_matrix1: Replacement matrix1, with median substitutions. (np.ndarray (Ndet, Namp, Namp)).

Raises#

ValueError :: Raised if the inputs have a mismatch in size.

run(inputCrosstalk, camera, inputDims, outputDims)#
