The metadata have been migrated to PDS4. The data themselves are unchanged. 1998-02-01T00:00:00.000Z 1998-02-28T23:59:00.000Z Science Derived Lunar Prospector Derived Spacecraft Altitude Data for Regional Field Maps Fields Magnetic Background Lunar Prospector Mission urn:nasa:pds:context:investigation:mission.lunar_prospector data_to_investigation Lunar Prospector Host urn:nasa:pds:context:instrument_host:spacecraft.lp is_instrument_host Magnetometer for LP Instrument urn:nasa:pds:context:instrument:lp.mag is_instrument Moon Satellite urn:nasa:pds:context:target:satellite.earth.moon data_to_target Primary Mission urn:nasa:pds:lp-mager-derived:data-moon-pos:moon_pos::1.0 data_to_ancillary_data urn:nasa:pds:lp-mager-derived:data-spacecraft-pos:pos98_02::1.0 data_to_ancillary_data LP-L-MAG-5-LUNAR-FIELD-BINS-V1.0:MAP98_02C_EAS data_to_derived_source_product 10.17189/1519725 PDS Planetary Plasma Interactions Node This is the first version converted to PDS4.

MAP98_02C_EAS.TAB 2003-09-02T19:14:40 19000 a23c01727fed8396cd1492847184c906 File naming convention: MAPyy_mm*_ttt.TAB, where yy indicates the year (98 or 99 for 1998 or 1999), mm indicates the month (01 for January, etc.), * indicates the map number for this month (A, B, etc.), and where ttt indicates the file type (ALT = Altitude),(EAS = East field component; NOR = North field component; RAD = Radial field component; TOT = total field.) Lunar Prospector Regional Field Maps Data at the Spacecraft East Field Component for 1998-FEB, Map: C 0 380 Interpolation and two-dimensional filtering are applied to the calibrated data to produce gridded field component data files on a surface defined by the slowly varying spacecraft altitude. The spatial resolution of the grid is chosen to be much less than the mean spacecraft altitude. The measured parameters consist of the three vector components of the lunar crustal magnetic field in East, North, and Radial (ENR) coordinates, the field magnitude, and the spacecraft altitude. The units of the field measurements are nanoTeslas (nT). 1 nT = 0.00001 Gauss. The units of the spacecraft altitude are kilometers (km). ENR coordinates are centered at the instantaneous spacecraft location with X directed eastward, Y directed northward, and Z directed radial to the Moon. Carriage-Return Line-Feed 4 0 50 Latitude 1 1 ASCII_Real 12 degrees Latitude at this grid point (South is negative; North is positive). East Longitude 2 14 ASCII_Real 11 degrees East longitude at this grid point. Magnetic Field 3 26 ASCII_Real 11 nT Altitude in kilometers. Data Points in Bin 4 38 ASCII_Real 11 Number of data points in this latitude/longitude bin. The bin size can be deduced from the difference between successive latitude and longitude values (e.g., 0.5 degrees by 0.5 degrees for altitudes near 100 km; 0.25 degrees by 0.25 degrees for altitudes near 25 km).
