data |
(can be a grouped_by data set) |
d15 |
the d15 column |
area |
the area (signal) column if want to use this as a calibration parameter (default is just the mean of the standards) |
standards |
a set of isotope standards Note: they are matched to the data by "category" (not by name) |
infer_ref_gas |
whether to infer reference gas (N2O) isotopic composition from the regression |
infer_bgrd |
whether to infer bacterial background from the regression |
introduces the column d15.cal and parameters p.15_stds, p.d15_m and p.d15_b as well as p.bgrd_area and p.bgrd_d15
implement single point correction
consider removing the storage of the regression parameters since they can be inferred from the others
