Methods Documentation

interpolate_variable(wavelengths, apertures)¶: Interpolate the SED to a variable aperture as a function of wavelength. This method should be called with an interpolating function for aperture as a function of wavelength, in log10 space.

classmethod read(filename, unit_wav=Unit("micron"), unit_freq=Unit("Hz"), unit_flux=Unit("erg / (cm2 s)"), order='nu')¶

Read an SED from a FITS file.

Parameters:

filename: str: The name of the file to read the SED from.
unit_wav: `~astropy.units.Unit`, optional: The units to convert the wavelengths to.
unit_freq: `~astropy.units.Unit`, optional: The units to convert the frequency to.
unit_flux: `~astropy.units.Unit`, optional: The units to convert the flux to.
order: str, optional: Whether to sort the SED by increasing wavelength (wav) or frequency (‘nu’).

scale_to_distance(distance)¶

Returns the SED scaled to distance distance

Parameters:	distance : float The distance in cm
Returns:	sed : SED The SED, scaled to the new distance

write(filename, overwrite=False)¶

Write an SED to a FITS file.

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