<!-- 11/23/2021 GEO/EAG Initial version
    09/26/2023
    Added new mission phases for mapping cycles.
    Added P-MIDR for polar MIDRs.
    Renamed attribute pds3_volume_id to original_pds_volume_id because many
    Magellan datasets were created using standards that predate PDS3.
    12/4/2024 GEO/EIS
    Added band_name, dsn_station_number, organization_id, and 
    received_polarization_type.
    Moved some 9/26/2023 comments from <Ingest_LDD>/<comment> to the text
    block you are reading now (above).
    Corrected typo "Harmononic" -> "Harmonic".

                    trim and checkout phase until completion of one cycle of radar
                    mapping (approximately 243 days). Started 1990-09-15 and ended

                    Acquisition of 'right-looking' SAR data was emphasized. Radio
                    occultation measurements were carried out on orbits 3212-3214.
                    A period of battery reconditioning followed completion of     
                    Cycle 2. Started 1991-05-16 and ended 1992-01-17.</value_meaning>

                    (approximately 243 days). Acquisition of 'stereo' SAR data   
                    was emphasized. The last orbit in the third cycle was orbit  
                    5747. Started 1992-01-24 and ended 1992-09-14.</value_meaning>

                    mapping cycle through an additional cycle of mapping.         
                    Acquisition of radio tracking data for gravity studies was    
                    emphasized. Radio occultation measurements were carried out  
                    on orbits 6369, 6370, 6471, and 6472. Because of poor        
                    observing geometry for gravity data collection at the         
                    beginning of the cycle, this cycle was extended 10 days beyond
                    the nominal 243 days. Orbits included within the fourth cycle
                    were 5748 through 7626. Periapsis was lowered on orbit 5752  
                    to improve sensitivity to gravity features in Cycle 4.

                    mapping cycle through achievement of a near-circular orbit.   
                    Circularization was achieved more quickly than expected; the  
                    first gravity data collection in the circular orbit was not   
                    scheduled until 11 days later. Orbits included within the    
                    aerobraking phase were 7627 through 8392. Started 1993-05-26

                    for gravity studies was emphasized. The first orbit in the   
                    fifth cycle was orbit 8393. Started on 1993-08-16 and ended on

            The radar_look_direction attribute provides the direction the radar
            antenna was pointing relative to the spacecraft ground track along 
            a given orbit. Most cases were Left or Right. Stereo indicates left
            looking with an incidence angle for stereo measurements. Maxwell is
            a special case for observing the Maxwell feature.
