hyperion.model.Image

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

Class to represent an image or set of images

Parameters :

nu : ndarray

The frequencies at which the image is defined, in Hz

val : ndarray, optional

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

unc : ndarray, optional

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

units : str

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).
x_max	Upper extent of the image in the x direction (in cm).
y_min	Lower extent of the image in the y direction (in cm).
y_max	Upper extent of the image in the y direction (in cm).
lon_min	Lower extent of the image in the x direction (in degrees).
lon_max	Upper extent of the image in the x direction (in degrees).
lat_min	Lower extent of the image in the y direction (in degrees).
lat_max	Upper extent of the image in the y direction (in degrees).
distance	Distance assumed for the image (in cm).
pix_area_sr	Pixel area (in steradians).
inside_observer	Whether the image was from an inside observer.
