sncosmo.MLCS2k2Source

class sncosmo.MLCS2k2Source(fluxfile, name=None, version=None)[source]

A spectral time series model based on the MLCS2k2 model light curves, using the Hsiao template at each phase, mangled to match the model photometry.

The spectral flux density of this model is given by

\[F(t, \lambda) = A \times M(\Delta, t, \lambda)\]

where _A_ is the amplitude and _Delta_ is the MLCS2k2 light curve shape parameter.

Note

Requires scipy version 0.14 or higher.

Parameters
fluxfilestr or obj

Filename (or open file-like object) of a FITS file containing 3-d array of spectral flux density values for a grid of delta, phase and wavelength values.
