Baseline Allocation
B The peak started or stopped on the baseline.
V The peak started or stopped with a valley drop-line.
P The peak started or stopped while the baseline was penetrated.
H The peak started or stopped on a forced horizontal baseline.
F The peak started or stopped on a forced point.
M The peak was manually integrated.
U The peak was unassigned.
Additional flags may also be appended (in order of precedence):
Character 3
D The peak was distorted.
A The integration was aborted.
U An under-range condition occurred.
O An over-range condition occurred.
Character 4
The fourth character describes the peak type:
S The peak is a solvent peak.
N The peak is a negative peak.
+ The peak is an area summed peak.
T Tangent-skimmed peak (standard skim).
X Tangent-skimmed peak (old mode exponential skim).
E Tangent-skimmed peak (new mode exponential skim).
m Peak defined by manual baseline.
n Negative peak defined by manual baseline.
t Tangent-skimmed peak defined by manual baseline.
R The peak is a recalculated solvent peak.
