BaseCube¶

class sedfitter.sed.BaseCube(valid=None, names=None, distance=None, wav=None, nu=None, apertures=None, val=None, unc=None)¶

A cube to represent a cube of models.

This consists of values and uncertainties as a function of wavelength, aperture, and models.

Parameters:

names : 1-d iterable, optional: The names of all the models in the cube
distance : ~astropy.units.Quantity, optional: The distance assumed for the values
wav : 1-d ~astropy.units.Quantity, optional: The wavelengths at which the SEDs are defined (cannot be used with nu)
nu : 1-d ~astropy.units.Quantity, optional: The frequencies at which the SEDs are defined (cannot be used with wav)
apertures : 1-d ~astropy.units.Quantity, optional: The ap for which the SEDs are defined
val : 3-d ~astropy.units.Quantity, optional: The values of the fluxes or polarization
unc : 3-d ~astropy.units.Quantity, optional: The uncertainties in the fluxes or polarization

classmethod read(filename, order='nu', memmap=True)¶

Read models from a FITS file.

Parameters:	filename: str The name of the file to read the cube from. order: str, optional Whether to sort the SED by increasing wavelength (wav) or frequency (‘nu’).

write(filename, overwrite=False, meta={})¶

Write the models to a FITS file.

Parameters:	filename: str The name of the file to write the cube to.
