	_getFluxes (self, inputData)

Detailed Description

Special-case convert manager for Gaia XP spectrophotometry catalogs,
that have fluxes/flux errors, instead of magnitudes/mag errors.  The input
flux and error values are in units of  W/Hz/(m^2) (Gaia Collaboration, Montegriffo et al. 2022).
The the flux and fluxErr fields in the output catalog have units of nJy.

_getFluxes()

lsst.meas.algorithms.convertRefcatManager.ConvertGaiaXpManager._getFluxes ( self, inputData )

protected

Compute the flux fields that will go into the output catalog.

Parameters
----------
inputData : `numpy.ndarray`
    The input data to compute fluxes for.

Returns
-------
fluxes : `dict` [`str`, `numpy.ndarray`]
    The values that will go into the flux and fluxErr fields in the
    output catalog.

Reimplemented from lsst.meas.algorithms.convertRefcatManager.ConvertRefcatManager.
