DESCRIPTION = " Lunar Prospector magnetometer (MAG) Level 2 Data. Selected and filtered time series data at 5 second intervals from the Lunar Prospector (LP) polar orbital mission to the Moon (January 1998 to July 1999). These data represent approximate measurements of the lunar crustal magnetic field with external (solar wind and magnetospheric) fields removed or minimized. Latitude / longitude coverage is limited to specific regions overpassed by the spacecraft during the selected intervals. Vector magnetic field components are given in two coordinate systems: Selenographic (SG) coordinates and east, north, and radial (ENR) coordinates. File naming convention: YY_DOY_NN.det, where YY is year number (98 or 99), DOY is day of year, and NN is orbit number on the selected day. Column 1: Hour of day in Universal time (to 4 decimal places) Column 2: BX in nanoTeslas; X component of the magnetic field in SG Coordinates. Column 3: BY in nanoTeslas; Y component of the magnetic field in SG Coordinates. Column 4: BZ in nanoTeslas; Z component of the magnetic field in SG Coordinates. Column 5: BE in nanoTeslas; East comp. of the magnetic field in ENR coordinates. Column 6: BN in nanoTeslas; North comp. of the magnetic field in ENR coordinates. Column 7: BR in nanoTeslas; Radial comp. of the magnetic field in ENR coordinates. Column 8: Lunar Latitude in degrees; north is positive. Column 9: Lunar east longitude in degrees. Column 10: Approximate altitude of spacecraft in kilometers." ^TABLE = "98_044_01.TAB" OBJECT = TABLE INTERCHANGE_FORMAT = ASCII ROWS = 577 COLUMNS = 10 ROW_BYTES = 89 OBJECT = COLUMN NAME = "HOUR" COLUMN_NUMBER = 1 UNIT = "HOUR" DATA_TYPE = ASCII_REAL START_BYTE = 1 BYTES = 9 DESCRIPTION = " Hour of day in Universal time (to 4 decimal places)."
