Data Set Overview
=================
This data set contains the data referred to
PHC Mission Phase

Data
====
Both data, scientific and housekeeping, are collected in this data
set. They referred to CODMAC Level 2.

Processing
==========
Only CODMAC Level 2 data are present in this data set.

Coordinate System
=================
The geometry items SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTOR
and SC_TARGET_VELOCITY_VECTOR provided in the label of the data
product are relative to the Earth Mean Equator and Equinox reference
frame of J2000.
SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the
PLANETOCENTRIC coordinate system. The target used is the comet 67P/C-G.
These parameters are computed at time t=START_TIME. Distances are given
in km, angles in degrees.

Data confidence is nominal, meaning that
                            all data have been validated by the
                            scientific team and found as expected.
                            Any exceptions are noted by the
                            DATA_QUALITY_ID. Moreover the data set
                            underwent a successful external review
