| DATA_SET_DESCRIPTION |
Data Set Overview:This data set contains derived data combining calibrated mass spectrareferred to FSS Mission Phase.Data:Both data, scientific and housekeeping, are collected in this dataset. They referred to CODMAC Level 5.The level 5 data product contains ion counts for mass spectra ateach observation site and ion counts for each of the main compoundsobtained from Ptolemy sniff operations made during the Philaefirst-science sequence.Processing:Only CODMAC Level 5 data are present in this data set.Mass spectra with the same mass range (using the same scan function)are summed to produce a single mass spectrum with calibrated mass range.In addition integer masses are assigned for the channel closest to theinteger mass.Ion counts were determined for each mass by using a rolling sum (n : 11for WGA 3, n : 7 for WGA 4) of the ion counts centered on the assignedmass (using the data set above). A single combined spectrum was producedfor each observation by summing WGA3 and WGA4, with values extrapolatedfor the missing ranges using the ratio of total ion counts in theoverlapping range.Coordinate System:The geometry items SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTORand SC_TARGET_VELOCITY_VECTOR provided in the label of the dataproduct are relative to the Earth Mean Equator and Equinox referenceframe of J2000.SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in thePLANETOCENTRIC coordinate system. These parameters are computed attime t:START_TIME. Distances are given in km, angles in degrees.
