CvD18

class paintbox.CvD18(wave=None, libpath=None, sigma=100, store=None, elements=None, norm=True)

Bases: paintbox.sed.PaintboxBase

Utility class for the use of CvD models.

This class provides a convenience paintbox interface to CvD models, producing a callable object that can be used together with other classes to produce more detailed SED models.

The CvD model files require pre-processing for use with paintbox, which may require an initial overhead of ~one minute, but the processed files can be reused for several files / runs if necessary it models are stored in disk.

Parameters

wave: ndarray, astropy.units.Quantity

Wavelength array of the model.

libpath: str

Path to the locations where CvD18 models are stored.

sigma: float

Velocity dispersion of the output in km/s. Default is 100 km/s (the minimum velocity dispersion allowed).

store: str

Directory where processed models are stored for reuse. If models are not found within store, models in the libpath are processed for use, and stored in this directory.

elements: list

Chemical abundances to be included in the model. Available elements are ‘Ba’, ‘C’, ‘Ca’, ‘Co’, ‘Cr’, ‘Cu’, ‘Eu’, ‘Fe’, ‘K’, ‘Mg’, ‘Mn’, ‘N’, ‘Na’, ‘Ni’, ‘Si’, ‘Sr’, ‘T’, ‘Ti’, ‘V’, ‘a/Fe’, ‘as/Fe’. Default is to use all elements except T (temperature of hot star) and ‘a/Fe’.

norm: bool

Normalize the flux of the processed models to the median. Default is True.
