   This dataset contains the engineering and scientific data derived from 
the measurements obtained by the HASI instrument during the Huygens probe 
mission at Titan on 14 January 2005. 

The data set id is HP-SSA-HASI-2-3-4-MISSION-V1.1. The file ERRATA.TXT
explains the differences with the previous archived data set
HP-SSA-HASI-2-3-4-MISSION-V1.0.

   The structure of the data set is described in the "Huygens HASI Experiment 
to Archive Interface Control Document" (HASI-EAICD) HASI-ICD-UPD-001.   

     In addition to the data themselves, the datasets contain a wide variety 
of supporting files for the Archive user; the major categories are 
documentation and calibration. In complaince with PDS standard these have 
been organized in five principal directories one level below the root: DATA,
CALIB, CATALOG, INDEX, DOCUMENT.
The directory DATA and CALIB are organized in subdirectories for each
HASI subssystems,containing data files relevant to the different measurements 
and derived parameters. 

  Huygens probe auxiliary data (e.g. aerodynamic coefficients, Probe physical 
properties, parachute characteristics) used for higher level product  
derivation are archived in the Huygens housekeeping (HK) data set.

  The official Huygens trajectory is the result of a common efford produced by
the Huygens Descent Trajectory Working Group (DTWG) and archived within the 
Huygens DTWG data set.
The HASI team has also performed independent reconstructions and vertical 
profiles of altitude and velocity are also provided in this data set as higher
level products.
