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 3.

Processing
==========
Only CODMAC Level 3 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. 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.
                            Please note, that the observations are
                            influenced by lander rotation. After the
                            second touchdown at 17:25 UTC only very few
                            particles were detected, which was caused
                            by the sensor hitting the comet surface. No
                            data after this event should be used for
                            science. Any additional exceptions are noted
                            by the DATA_QUALITY_ID.
