Introductory Information: -- Version description -- Disclaimer -- Sources Pck Data: -- Orientation constants Asteroid 1992KD -- Radii for Asteroid 1992KD Version description -------------------------------------------------------- This file was created on June 28, 1999. It replaces ds1_1992KD_v01.tpc, which was released April 13, 1999. This file contains data only for Asteroid 1992KD (Braille). This is a preliminary PCK containing placeholder values for pole direction and prime meridian location. Disclaimer -------------------------------------------------------- This constants file may not contain the parameter values that you prefer. Note that this file may be readily modified by you or anyone else. NAIF suggests that you inspect this file visually before proceeding with any critical or extended data processing. NAIF requests that you update the `by line' and date if you modify the file. Sources -------------------------------------------------------- The sources for the constants listed in this file are: 1) Statement by B. Buratti et al at DS1 Science Team Meeting; 4/012/99. 2) Statement by J. Oberst et al at DS1 Science Team Meeting; 4/12/99. 3) "1992 KD Lightcurve Observations from Australia/Argentina Team Meeting Report, June 23, 1999" -------------------------------------------------------- Asteroid 1992KD The inertial reference frame for these constants is J2000; this is the default reference frame for PCK orientation data. The epoch of the constants is J2000; this is Julian ephemeris date (JED) 2451545.0. The NAIF integer code for 1992KD is 2009969. See the NAIF_IDs required reading for further information on NAIF integer codes. The pole has been arbitrarily chosen to point toward ecliptic north at the J2000 epoch. The RA and DEC below are those of the ecliptic north pole in J2000 coordinates. The prime meridian W0 term has been arbitrarily chosen to be zero at the J2000 epoch. The W1 term corresponds to a period of 226 hours, as indicated by (3). The significance of the numbers given below is far lower than indicated by the number of digits shown. \begindata BODY2009969_POLE_RA = ( 270.0 0 0 ) BODY2009969_POLE_DEC = ( 66.5607088888889 0 0 ) BODY2009969_PM = ( 0 38.230088495575 0 ) \begintext The radii are from (1).
