Paper Abstract

The Mid Infrared Instrument of the James Webb Space Telescope is equipped with an integral field unit (IFU) spectrometer. The optical distortion in the image slicing and dispersive optics leads to non-uniform sampling and a catenation of the spatial and spectral information on the detector plane. To enable the translation of detector data to the three-dimensional data cube representing the two spatial and the spectral sky dimension, we have built two software tools: The first is miri cube, an image reconstruction programme which translates the detector data back into the sky cube. The second is an extended version of SpecSim, an IFU simulator which simulates the image slicing and dispersion based on optical models of the instrument. With these tools we are able to determine and implement the correct strategy for the end-to-end calibration of spectroscopy data during the on-ground cryogenic test campaign.
