instFluxErrToMagnitudeErr(instFlux, instFluxErr, localCalib, localCalibErr)

Convert instrument flux err to nanojanskys.

Parameters:

instFluxndarray or Series

Array of instrument flux measurements.

instFluxErrndarray or Series

Errors on associated instFlux values.

localCalibndarray or Series

Array of local photometric calibration estimates.

localCalibErrndarray or Series

Errors on associated localCalib values.

Returns:

calibMagErr: ndarray or Series

Error on calibrated AB magnitudes.

instFluxErrToNanojanskyErr(instFlux, instFluxErr, localCalib, localCalibErr)

Convert instrument flux to nanojanskys.

Parameters:

instFluxndarray or Series

Array of instrument flux measurements.

instFluxErrndarray or Series

Errors on associated instFlux values.

localCalibndarray or Series

Array of local photometric calibration estimates.

localCalibErrndarray or Series

Errors on associated localCalib values.

Errors on calibrated flux measurements.

instFluxToMagnitude(instFlux, localCalib)

Convert instrument flux to nanojanskys.

Parameters:

instFluxndarray or Series

Array of instrument flux measurements.

localCalibndarray or Series

Array of local photometric calibration estimates.

Returns:

calibMagndarray or Series

Array of calibrated AB magnitudes.

instFluxToNanojansky(instFlux, localCalib)

Convert instrument flux to nanojanskys.

Parameters:

instFluxndarray or Series

Array of instrument flux measurements.

localCalibndarray or Series

Array of local photometric calibration estimates.

Returns:

calibFluxndarray or Series

Array of calibrated flux measurements.

multilevelColumns(data, columnIndex=None, returnTuple=False)

Returns columns needed by functor from multilevel dataset.

To access tables with multilevel column structure, the DeferredDatasetHandle or InMemoryDatasetHandle needs to be passed either a list of tuples or a dictionary.

Parameters:

datavarious

The data as either DeferredDatasetHandle, or InMemoryDatasetHandle.

columnIndex (optional): pandas `~pandas.Index` object

Either passed or read in from DeferredDatasetHandle.

`returnTuple`bool

If true, then return a list of tuples rather than the column dictionary specification. This is set to True by CompositeFunctor in order to be able to combine columns from the various component functors.
