This data set contains  derived data combining calibrated mass spectra        
referred to FSS Mission Phase.                                                
                                                                              
Data

Both data, scientific and housekeeping, are collected in this data            
set. They referred to CODMAC Level 5.                                         
                                                                              
The level 5 data product contains ion counts for mass spectra at              
each observation site and ion counts for each of the main compounds           
obtained from Ptolemy sniff operations made during the Philae                 
first-science sequence.

==========                                                                    
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 the        
integer mass.                                                                 
Ion counts were determined for each mass by using a rolling sum (n = 11       
for WGA 3, n = 7 for WGA 4) of the ion counts centered on the assigned        
mass (using the data set above). A single combined spectrum was produced      
for each observation by summing WGA3 and WGA4, with values extrapolated       
for the missing ranges using the ratio of total ion counts in the             
overlapping range.
