hyperion.model.Image

class hyperion.model.Image(nu, val=None, unc=None, units=None)

Class to represent an image or set of images

Parameters

nundarray

The frequencies at which the image is defined, in Hz

valndarray, optional

The values for the image. The last dimensions should match the number of frequencies.

uncndarray, optional

The uncertainties for the image values. The last dimensions should match the number of frequencies.

unitsstr

The units of the values

Attributes

wav	The wavelengths for which the image is defined (in microns).
nu	The frequencies for which the image is defined (in Hz).
val	The image values (fluxes, flux densities, surface brightness, or polarization) in the units given by the .unit property.
unc	The uncertainties on the image values in the units given by the .unit property.
unit	The units of the image values.
x_min	Lower extent of the image in the x direction (in cm).
