Each probe could be fed by a bias current as is typically done on +electric field instruments in tenuous plasmas, or be disconnected from the bias circuitry to +ensure a good zero bias current (floating probes) as is typically done on sounding rockets. +Bias currents were used in the early part of the mission, but when the comet ionosphere +developed, the floating mode was found to give much more consistent data. Only data from +the floating mode have been used for providing E-field data, and only when both probes are +sunlit. + +The booms are not equal in length (2.24 and 1.62 m) and mounted on a big spacecraft (solar +panel wingspan 32 m), so one cannot expect LAP to provide a useful DC electric field estimate. +A moving average of the E-field over 32 s is therefore subtracted from the data in the EFL files. +The effective bandwidth of the data therefore is about 0.03 Hz to 20 Hz, the upper +limit set by the analog anti-aliasing filters. Note that the filtering may distort the lowest +frequencies. + +There are no external comparison data for assessing the absolute accuracy of the LAP E-field +measurements. The data themselves look very clean and well behaved [Karlsson et al., 2017; +André et al, 2017], with very little of common mode signal remaining, despite the s/c poten tial +being both high and highly variable. The technique with floating probes is proven on numerous +sounding rockets in the terrestrial ionosphere [Maynard, 1998]. +</Description> + <Contact> + <PersonID>spase://CDPP/Person/Anders.Eriksson</PersonID> + <Role>PrincipalInvestigator</Role> + </Contact> + <Contact> + <PersonID>spase://CDPP/Person/Erik.Johansson</PersonID> + <Role>DataProducer</Role> + </Contact> + <InformationURL> + <Name>RPC LAP User Guide</Name> + <URL>http://amda.irap.omp.eu/help/parameters/RO-IRFU-LAP-UG.PDF</URL> + </InformationURL> + <InformationURL> + <Name>ROSETTA RPC-LAP to Planetary Science Archive Interface Control Document</Name> + <URL>http://amda.irap.omp.eu/help/parameters/RO-IRFU-LAP-EAICD_2_0_1_PDF_A.PDF</URL> + </InformationURL> + </ResourceHeader> + <AccessInformation> + <RepositoryID>spase://SMWG/Repository/CDPP/AMDA</RepositoryID> + <Availability>Online</Availability> + <AccessRights>Restricted</AccessRights> + <AccessURL> + <URL>http://amda.cdpp.eu</URL> + </AccessURL> + <Format>NetCDF</Format> + </AccessInformation> + <ProviderName>PSA</ProviderName> + <ProviderResourceName>RO-C-RPCLAP-5-xxx-DERIV2-V1.0</ProviderResourceName> + <InstrumentID>spase://CDPP/Instrument/AMDA/Rosetta/LAP</InstrumentID> + <MeasurementType>ThermalPlasma</MeasurementType> + <TemporalDescription> + <TimeSpan> + <StartDate>2014-03-24T08:12:59Z</StartDate> + <StopDate>2016-09-30T10:31:16Z</StopDate> + </TimeSpan> + <Cadence_Min>PT0.05S</Cadence_Min> + <Cadence_Max>PT35S</Cadence_Max> + </TemporalDescription> + <Parameter> + <Name>e-field comp</Name> + <ParameterKey>ros_lap_efl</ParameterKey> + <Description>Electric field component, calculated on ground by + taking the difference between floating probe measurements on both probes and + dividing by distance, (V_P2-V_P1)/L.
