title = "Blur remediation in NEAR MSI images",
abstract = "Due to contamination on the outer optic of the NEAR-Shoemaker Multispectral Imager (MSI), all surface-resolved images of Eros acquired by MSI had wavelength-dependent degradation. The MSI team designed and implemented a preliminary correction for the blur during mission operations and archived the results with the original camera data. While successful for most filters, the preliminary correction had edge effect artifacts and was less effective for the 450 and 1050 nm passbands. Here we implement a new correction, based on the MSI team's original process, to improve the blur remediation for all MSI filters, particularly those at the extreme wavelengths. The new method improves the effective resolution of the deblurred images over the preliminary remediation for all filters. Moreover, for all filters, our method preserves the 21–39% of the pixels that were lost (or obscured by artifacts) with the preliminary remediation. We apply the new method to the complete MSI dataset of resolved Eros images and archive the results for future scientific use.",

This work was supported by NASA under Contract NNH18ZDA001N-PDART issued through the Planetary Data, Archiving, Restoration, and Tools program. Funding Information: This work comes two decades after the end of the NEAR mission, the success of which was due to a large number of individuals in the operational and scientific teams. Their efforts provided the exceptional dataset we attempted to improve. The work here builds directly off the original remediation developed by the MSI team, specifically Han Li and Mark Robinson, during NEAR operations. We also thank Beth Clark for her insight and reviewing the manuscript. The original image data used in this work are archived in the Planetary Data System Small Bodies Node (Murchie, 2001).
