Planetary Data System
Description:
Time-averaged spacecraft position and calibrated 3-axis magnetic
field samples in Mercury Body Fixed (MBF) coordinates. The data are
tagged with latency corrected UTC and MET time stamps at the center of
each interval. The MBF CDR is derived from the Science CDR for this
coordinate system with time averages computed within 1, 5, 10, and 60
s intervals.

Description:
Time-averaged spacecraft position and calibrated 3-axis magnetic
field samples in Mercury Solar Orbital (MSO) coordinates. The data are
tagged with latency corrected UTC and MET time stamps at the center of
each interval. The MSO RDR is derived from the Science CDR for this
coordinate system with time averages computed within 1, 5, 10, and 60
s intervals.

Planetary Data System
Description:
Time-averaged spacecraft position and calibrated 3-axis magnetic
field samples in Radial-Tangential-Normal (RTN) coordinates. The
spacecraft postion is given by the radial distance from Sun center,
northward latitude above the instantaneous ecliptic plane, and azimuth
angle of the spacecraft in the instantaneous ecliptic plane with
respect to the Earth-Sun line, positive in direction of the Earth's
orbital motion. The data are tagged with latency corrected UTC and MET
time stamps at the center of each interval. The RTN RDR is derived
from the Science CDR for this coordinate system with time averages
computed within 1, 5, 10, and 60 s intervals.

TITAN is a computer program for calculating the interactions of a dilute plane-parallel medium with electromagnetic radiation. It includes all atomic processes: absorption, recombination, diffusion, excitation, deexcitation of atoms and ions, heating and cooling of the gas, and it solves the radiation transfer, in order to obtain the spectra reemitted by the medium. It handles plan parallel slabs in non LTE steady state, for various physical conditions and various illuminations, valid in many astrophysical situations. It is specifically designed for warm-hot (8000 to 10**8 K) and thick media (till an electron scattering optical depth of several tens) emitting and absorbing in the X-ray range (density from 10**5 to 10**14 cm-3). It computes the physical parameters, ionisation degrees, temperature, density, and the spectrum of the radiated light in each point of the slab, by solving simultaneously the ionisation equations, the equations of statistical equilibrium, the thermal equations and the radiation transfer, using iteration processes.
Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee" helicoidal antenna, half of which being Right Handed (RH) polarized and the other half being Left Handed (LH) polarized. Four receivers are currently connected to the NDA, sampling data in spectral ranges within 5 to 80 MHz.
