                    This product, PVO_OETP_ELECTRON_HIGHRES_1125.TAB, was originally released in 2002 
                    as part of the PDS3 PVO-V-OETP-3-HIRESELECTRONS-V1.0 data set. 
                    The metadata have been migrated to PDS4. The data have been converted 
                    to ASCII, but the data values are unchanged.
