A. 2022 DSN ionospheric calibrations for MESSENGER radio science observations, migrated from the original PDS3 archive. Data from 2012-01-01T06:16:00.001Z to 2012-02-01T09:04:00.000Z. 2022-05-20 1.0 These data have been migrated from PDS3 PRODUCT_ID MESS_RS_2012001_032_DP_ION in data set MESS-V/H-RSS-1-EDR-RAWDATA-V1.0 to PDS4. The data file has not been changed; a new PDS4 label was created as part of the migration process. 2012-01-01T06:16:00.001Z 2012-02-01T09:04:00.000Z Calibration Calibrated DSN ionospheric calibrations for MESSENGER radio science observations, migrated from the original PDS3 archive.
