<h2> Pioneer 11  Ephemeris data at AMDA </h2>


<UL>

  <li> Pioneer 11 Ephemeris data are taken from the PDS (Planetary Data System) 
    <a href="http://ppi.pds.nasa.gov/index.jsp" TARGET=_BLANK>site</a>

  <li> Available parameters :
    <UL>
      <li> <b>r</b> : Range of the spacecraft from the Jupiter center of mass in units of Jupiter radii where 1 Rj = 71492 km
      <li> <b>lat</b> : Planetographic latitude of the spacecraft in degrees
      <li> <b>lon_east</b> : Planetographic east longitude of the spacecraft in degrees
      <li> <b>LT</b> : Angle between the observer's (spacecraft) sub-Jupiter meridian and the anti-sunward meridian, measured in the Jovian equatorial plane in the direction of planetary rotation. The local hour angle is converted to a decimal hour (one hour equal to fifteen degrees longitude). The sun meridian is defined to be noon (12.000), with midnight (0.000) opposite it. Dawn (6.000) and dusk (18.000) are where the sun rises and sets according to the planet's rotation
