Data Set Overview=================The PV-OIMS low resolution dataset contains data from the Orbiter IonMass Spectrometer (OIMS) experiment for orbits 1-2996, including datafor the period periapsis +/- 30 minutes for each orbit. The datasetis divided into multiple files, each of which contains 1 orbit. Theuser should be able to easily get to any desired orbit by selecting theappropriate file.The user should be aware that some of the data columns have beencoded. For example, the values -999999 is the missing data value forthat point.column type bytes description========================== ========================================date integer 5 Date given in the format YYDOY where YY is the year and DOY is the day-of-year (Jan 1 =1)UT float 10 Universal Time second of dayorbit integer 7 PVO orbit numberperisecs float 10 Seconds after periapsis, negative before periapsisden_1 integer 8 Number density of 1 AMU particleden_2 integer 8 Number density of 2 AMU particleden_4 integer 8 Number density of 4 AMU particleden_8 integer 8 Number density of 8 AMU particleden_12 integer 8 Number density of 12 AMU particleden_14 integer 8 Number density of 14 AMU particleden_16 integer 8 Number density of 16 AMU particleden_18 integer 8 Number density of 18 AMU particleden_28 integer 8 Number density of 28 AMU particleden_30 integer 8 Number density of 30 AMU particleden_32 integer 8 Number density of 32 AMU particleden_44 integer 8 Number density of 44 AMU particle
