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.
