ROSETTA-ORBITER CHECK GIADA 2 EAR1 EARTHSWINGBY1 V1.0

This volume contains Experiment Data acquired by GIADA during 'Earth swing-by 1' phase. More in detail it refers to the data provided during the following in-flight tests: 'Passive Payload Checkout n. 0' (PC0) held on 28/29-03-2005. 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.
