Functions
double	lsst::cpputils::nanojanskyToABMagnitude (double flux)
	Convert a flux in nanojansky to AB magnitude.
double	lsst::cpputils::ABMagnitudeToNanojansky (double magnitude)
	Convert an AB magnitude to a flux in nanojansky.

Variables
const double	lsst::cpputils::referenceFlux = 1e23 * pow(10, (48.6 / -2.5)) * 1e9
	The Oke & Gunn (1983) AB magnitude reference flux, in nJy (often approximated as 3631.0).

Detailed Description

Utilities for converting between flux and magnitude in C++.

Use astropy.units ABmag and nJy for converstions in python:

import astropy.units as u
mag = (flux*u.nJy).to_value(u.ABmag)
flux = (mag*u.ABmag).to_value(u.nJy)
