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

LAP operations are described in the operations report, IRFU-ROS-OPR-ESC2
in the DOCUMENT/FLIGHT_REPORTS directory of this archive.


B. Dataset status
-----------------

This dataset 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 C 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. At a later stage, a DERIVED data
archive will be delivered, providing directly useful scientific
quantities (e.g. plasma density, wave spectra, electron temperature).

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-x_y_z, in the DOCUMENT
directory.

For general caveats, see the EAICD in the DOCUMENT directory. For
specifics of this mission phase, see the operations report,
IRFU-ROS-OPR-ESC2 in the DOCUMENT/FLIGHT_REPORTS directory.

Other caveats:

a. Until the end of operations at the comet, the first priority of the
   LAP team will have to be the science operations of the instrument, to
   make sure there will be useful data to archive. The archived data
   set is complete, and 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 dataset is strongly encouraged to
   contact a LAP CoI for cooperation.

These data are uncalibrated raw
        data, i.e. digital output of the instrument. As such, the confidence
        level is very high.
