(Bulk) estimates of (ghg) fluxes from online concentration measurements with non-steady-state closed chambers. The function tries to find stable linear conditions in concentration change by fitting many regressions to the data and automatically detects and excludes rapid concentration fluctations.

The function allows to adjust fitted R_eco models by eliminating the maximum R_eco flux as long as the p.value of the linear model of the residuals regressed against original fluxes is above a given threshold. In addition models with parameters that went astray may be skipped. The default is that R_eco models with t1 > 20 are omitted.

The function basically takes calibration gas measurements and extracts the calibration gas measurements that have been carried out temporally close to a real data measurement and calculates the standard deviation of the calibration gas measurements. The obtained range limits can be used in flux as a quality parameter (via range.lim).
