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

LAP operations are described in the operations report,
IRFU-ROS-OPR-CR4B 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 primary instrument data,
calibrated to physical units (volts and amperes) and with instrumental
offsets removed. See the caveats in Section D below for data use.


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

The data can be used for scientific analysis, but this requires some
familiarity with this type of data.

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-CR4B 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
instrument outputs in volts and amperes, calibrated and corrected for
instrument offsets to the greatest extent possible. Offsets are
determined onboard and removed from CALIBRATED data on ground but
still remains in EDITED data.
