Standard:

01:	18:1	Overlaps with PG. It is removed because of the NL_PChead_60*0.5>Precursor rule.
		Only one time, a peak in the tailing was identified as 18:1.		
		The other two times, the tailing peak was removed, since the +1 isotopic
		peak seems to overlap with something else, and is much too strong.

02:	Everything detected.

03: 	18:1	Same reason like in 01.


Biological:
Three FPs were detected. SM identification is not so reliable concerning the frequency
of the occurrence of the hits - there is quite often noise.
With overlapping PG species, it might improve the amount of SM hits by alleviating the rule
NL_PChead_60*0.5>Precursor
But this may cause more false positives.
