Class ArraySourceSpectrum

spec = ArraySpectrum(numpy array containing wavelenght table, numpy array containing flux table, waveunits, fluxunits, name=human-readable nickname for spectrum, keepneg=True to override the default behavior of setting negative flux values to zero)

source code

Create a spectrum from arrays.

Parameters:

wave - Wavelength array
flux - Flux array
waveunits (units.WaveUnits or subclass) - Units of wave
fluxunits (units.FluxUnits or subclass) - Units of flux
name (string) - Description of this array
keepneg (bool) - If true, negative flux values will be retained; by default, they are forced to zero
wave,flux (Numpy array with numerical data)

Overrides: object.__init__
