  • "scalar": 0-dimensional extracted values from the extraction aperture, at the wavelength of interest (if a spectroscopic calculation)
  • "1d": 1-dimensional spectral outputs (single-valued, if the calculation is an imaging calculation)
  • "2d": 2-dimensional detector images
  • "3d": 3-dimensional flux cubes of the input scene, created from the scene definition. For IFU modes only, also 3-dimensional reconstructed data cube of the output fluxes.
  • "input": A complete copy of the input dictionary
  • "information": The configured exposure properties of the calculation
  • "warnings": all warnings produced by the Engine
  • "transform": WCS information about the 2D output products.
  • "debugarrays": (optional)

In addition, if the code pandeia.engine.perform_calculation() is run with the "as_fits" keyword set to True, the 1d, 2d, and 3d output dictionaries will be formatted as FITS HDULists.

The scalar outputs are a superset of the values the Webapp produces in the Results tab.

The following code block will (given an result dictionary named 'result') print out results.
