Synthetic MISE Data for Radiation Robustness Analysis

This dataset contains synthetic observations similar to those that will be produced by the Mapping Imaging Spectrometer for Europa (MISE) instrument. The dataset was created by taking visible Galileo Solid-State Imaging (SSI) experiment observations resized to 300x300 pixels, using pixel intensity as a proxy for albedo, and linearly mixing two 451-channel spectra in proportion to albedo for each pixel. The contents of this directory include the original SSI images and PDS label files, rescaled versions of the images, and the spectral cubes in HDF5 format corresponding to synthetic MISE digital number (DN) measurements. The cube files contain two datasets, "cube" containing the DN values, and "wavelengths," which holds the wavelength in nanometers corresponding to each value in a spectrum. The dataset was created to evaluate the radiation robustness of the Reed-Xiaoli (RX) algorithm used for spectral anomaly detection. For the radiation robustness analysis, only the first 421 channels of the spectra are used. The full dataset size is roughly 781 MB.
