A. Operations overview
----------------------

LAP operations are described in the operations report,
IRFU-ROS-OPR-ESC3 in the DOCUMENT/FLIGHT_REPORTS directory of this
data set.


B. Data set status
------------------

This data set contains scientifically useful data from the Rosetta
RPC-LAP instrument. The data contained are high-level data in
physical units, such as electron density, electron temperature,
spacecraft potential, and downsampled time series of current and
voltage measurements. See the caveats in Section D below for data
use.


C. Scientific use
-----------------

For information on exact data products (science data, geometry files,
housekeeping), calibration, file formats and file naming conventions,
etc., consult the EAICD, RO-IRFU-LAP-EAICD, in the DOCUMENT
directory. For the specifics of this mission phase, see the operations
report, IRFU-ROS-OPR-ESC3 in the DOCUMENT/FLIGHT_REPORTS directory.


D. Caveats
----------

This section covers caveats relevant for this specific data set. For
general caveats, see the EAICD in the DOCUMENT directory.


D.1. General caveat
-------------------

The archived data set is complete, but it has not been possible to
scan every part of it for every possible problem before delivery, so
there may be numerous data quality issues in addition to this list.
While the data clearly have a great science potential, analysis has to
be done with great care. Anybody using the present data set is strongly
encouraged to contact a LAP CoI for cooperation.

Data in this archive are
plasma parameters derived from LAP CALIBRATED data as described in the
EAICD. Cross-calibration with RPCMIP has been used to tune the
analysis algorithms, but disturbances from spacecraft-plasma
interactions and other issues may still cause significant
differences.
