The dust particle data are provided for dust instrument (SDC) calculations. The reference frame for all quantities is the Earth Mean Equator, dynamical equinox of epoch J2000 (NAIF/SPICE name = 'J2000') frame. The heliocentric Z-component of the dust particle, in the Earth Mean Ecliptic and Equinox of the Epoch J2000 (NAIF/SPICE name = 'ECLIPJ2000') frame, is assumed to be zero. This comma-separated table includes the following columns: One column of ephemeris time (ET, s past J2000 epoch) Two columns of time (calendar and DOY) Three (XYZ) columns of heliocentric spacecraft position (km) Three (XYZ) columns of heliocentric spacecraft velocity (km/s) Three (XYZ) columns of heliocentric dust velocity (m/s) Three (XYZ) columns of spacecraft-centric dust velocity (m/s) " OBJECT = COLUMN COLUMN_NUMBER = 1 NAME = "ET" DESCRIPTION = "Ephemeris time (TDB), seconds past J2000 epoch (2001-01-01 12:00:00 UTC)" START_BYTE = 1 BYTES = 16 DATA_TYPE = ASCII_REAL FORMAT = "F16.3" UNIT = "S" END_OBJECT = COLUMN OBJECT = COLUMN COLUMN_NUMBER = 2 NAME = "UTC_CAL" DESCRIPTION = "UTC in ISO Calendar format; conversion from ET uses NAIF/SPICE LEAPSECOND kernel naif0010.tls" START_BYTE = 18 BYTES = 19 DATA_TYPE = TIME FORMAT = "A19" END_OBJECT = COLUMN OBJECT = COLUMN COLUMN_NUMBER = 3 NAME = "UTC_DOY" DESCRIPTION = "UTC in ISO Day Of Year (DOY) format; conversion from ET uses NAIF/SPICE LEAPSECOND kernel naif0010.tls" START_BYTE = 38 BYTES = 17 DATA_TYPE = TIME FORMAT = "A17" END_OBJECT = COLUMN OBJECT = COLUMN COLUMN_NUMBER = 4 NAME = "X_SC_POSITION" DESCRIPTION = "Cartesian X component of the vector of New Horizons spacecraft heliocentric position in the Earth Mean Equator J2000 (EMEJ2000) frame."
