This file is to select/deselect measurements from the autosampler file by setting their value of AMS_note to 1 and 0, respectively.
This is then used in several processing/visualization steps to specify the samples under consideration.

AMS_note_general 
is to mark those samples that should be selected for analysis in general.
The others contain either no data, are double or corrupted.
A description/comment is given in the adjacent column.

AMS_note_general_no_qc
same as AMS_note_general, but excluding the different qc samples

11years: 11 years samples to be picked
11years_FB: 11 years and the corresponding Fieldblanks
11years_FB_MilliQ: 11 years and the corresponding Fieldblanks + Extracted MilliQ
11years_to2019: 11 years samples without 2020 and 2021; for EMPA-IC comparison, as these not available for those years

BB : BB samples to be picked

SDE: SDE samples
SDE_to2019: SDE samples without 2020 and 2021; for EMPA-IC comparison, as these not available for those years
