- start_col
column with datetime when the measurement started
- end_col
column with datetime when the measurement ended
- datetime_col
column with datetime of each concentration measurement
- conc_col
column with gas concentration data
- fluxid_col
column with ID of each flux
- t_zero
time at which the slope should be calculated
