                This file, PVO_OMAG_PSENS_24S_3992.TAB, contains Pioneer Venus (PVO) magnetometer (OMAG)
                data averages (24 sec) acquired after the multiplexer anomaly that allowed
                data from only a single sensor (P-sensor) to be returned to the ground. The data has been calibrated to account for gains only.
                The data are given in units of nanoTesla. These data have been averaged over two spin period intervals
                on one spin period centers. The time tag given to each record is the project
                assigned time value for the spin period (UADS time tag).

                    This product, PVO_OMAG_PSENS_24S_3992.TAB, was originally released in 1995 
                    as part of the PDS3 PVO-V-OMAG-4-P-SENSOR-24SEC-V1.0 data set. A revised 
                    version of this data set (PVO-V-OMAG-4-P-SENSOR-24SEC-V2.0) was released
                    in 2023. This is the first version of these data in PDS4. The metadata have 
                    been migrated to PDS4. The data are the same as those in the 2023 release.

in the PVO Inertial Spacecraft Coordinate System (PVO_ISCC). The Z axis is    
defined to be anti-parallel to the spacecraft spin axis during orbital        
operations. This vector has been averaged over two spin periods from the      
high resolution data.
