Data Set Overview Contents: A. Operations overview B. Dataset status C. Scientific use A. Operations overview This dataset contains Rosetta LAP calibrated data from the Rosetta flyby of asteroid 21 Lutetia. Operation dates: July 7 13, 2010 Objective: science, diagnostics Environment: solar wind at 2.7 AU Scientific potential of LAP data acquired: Good. Description of operations: The LAP operations are further described in the r^ant operations report, IRFUROSOPRLUT in the DOCUMENT/FLIGHT_REPORTS directory of this archive. LAP was on during the full Lutetia flyby, monitoring the solar wind density variations through the measurement of the probetospacecraft potential most of the time, with some operations also in Langmuir probe sweep mode to provide information on photoemission. From CA2h50min to CA+3h10min, LAP was in burst mode with higher telemetry rate, sampling the probetospacecraft potential at 57.8 s1. Outside this time span, LAP had normal telemetry rate, usually sampling at 0.9 s1. In both modes, LAP also produces shorter records at 18.75 kHz sampling typically every 32 s (burst mode) or 160 s (normal mode). One hour after closest approach, LAP handed over probe 2 to MIP for use in the MIP LDL (Long Debye Length) mode. During this period, the only LAP data available derives from probe 1. More LDL operations were run at the end of operations. Operations were fully nominal. The LAP data acquired are good and scientifically useful, though any user must take great care of the limitations set by the varying pointing, the tenuous plasmas, and the spacecraftplasma interaction. In particular, the large pointing variations at closest approach make any data analysis here extremely difficult and prone to spurious effects. B.
