DATA_SET_NAME ROSETTA-ORBITER STEINS GIADA 2 AST1 STEINSFLYBY V1.0

DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION The format of data reported in GIADA data sets is the same for all mission phases. Data reported by GDS and IS are due to noise as no dust event is expected in this mission phase. MBS frequency changes, once normalised for frequency vs. temperature dependence, if present, are due to deposition of contaminants existing in the S/C environment. Housekeeping and Calibration data from all GIADA sub-systems are useful to evaluate instrument health and behaviour when compared with similar data acquired during other mission phases.

CONFIDENCE_LEVEL_NOTE The data reported in this data set have been converted from ADC counts to engineering values. The quality of the Housekeeping and Calibration data is good. Scientific data are due to noise, as no grain event is expected during this mission phase. These data must be only considered to evaluate GIADA behaviour and not as real scientific data. See RO-GIA-OACUPA-RP-112-1 (reported in DOCUMENTation dir) for evaluations on GIADA behaviour during this mission phase.
CITATION_DESCRIPTION A.Rotundi and the International GIADA Consortium, RO-A-GIA-2-AST1-STEINSFLYBY-V1.0, NASA Planetary Data System, 2007.
ABSTRACT_TEXT The report provides the results from GIADA experiment during theRosetta Steins Flyby. Asteroid Steins was the first dedicated scientific target of the Rosetta mission. Unfortunately the three subsystem of GIADA were not able to study Steins, so GIADA during asteroid flyby was in a non-nominal operational configuration, i.e.only the impact sensor operational and the cover closed. Therefore, during Steins fly-by we have only checked the status of GIADA instrument. Scientific operations targeting the asteroid started on 1 Sept. 2008 and ended on 10 Sept. 2008 and the Closest approach was on 5 Sept. 2008 at 18:38:20 UTC. Actually GIADA was in operation only the 5th Sept. 2008 just for 15 minutes. It also contains documentation which describes the GIADA experiment. The data reported in this data set have been converted from ADC counts to engineering values. The quality of the Housekeeping and Calibration data is good. Scientific data are due to noise, as no grain event is expected during this mission phase. These data must be only considered to evaluate GIADA behaviour and not as real scientific data. Data reported by GDS and IS are due to noise as no dust event is expected during this mission phase. MBS frequency changes, once normalised for frequency vs. temperature dependence, if present, are due to deposition of contaminants existing in the S/C environment. Housekeeping and Calibration data from all GIADA sub-systems are useful to evaluate instrument health and behaviour when compared with similar data acquired during other mission phases.
