Bases: IsrCalib

Definition for the TransmissionCurve format used as inputs.

Parameters

filenamestr

Filename of a transmission curve dataset.

Methods Summary

fromTable(tableList)	Construct intermediate transmission curve from a list of input tables.
getTransmissionCurve()
setMetadata(metadata)	Store a copy of the supplied metadata with this calibration.
setTransmissionCurveRepresentation()	Construct transmission curve representation from the data that was read.
writeFits(outputFilename)	Write the transmission curve data to a file.

Methods Documentation

classmethod fromTable(tableList)

Construct intermediate transmission curve from a list of input tables. Only the first table is used.

Parameters

tableListlist [astropy.table.Table]

List containing input tables.

Returns

caliblsst.ip.isr.IntermediateTransmissionCurve

The final calibration.

getTransmissionCurve()

setMetadata(metadata)

Store a copy of the supplied metadata with this calibration.

Parameters

metadatalsst.daf.base.PropertyList

Metadata to associate with the calibration. Will be copied and overwrite existing metadata.

setTransmissionCurveRepresentation()

Construct transmission curve representation from the data that was read.

Raises

RuntimeError

This is raised if no table data exists in the calibration, if there are array length mismatches, or if the wavelength sampling for multi-amp tables differ.

writeFits(outputFilename)

Write the transmission curve data to a file.

Parameters

outputFilenamestr

Destination filename.

Returns

outputFilenamestr

The output filename actually used.

Raises

RuntimeError

Raised if no transmission curve can be created.
