In the case of instantaneous periods (video counting) the sum of daily values is done by the fun_report_mig_mult method and the value indicated in method is "sum". If any migration monitoring period is longer than a day, then the migration is split using the fun_report_mig_mult_overlaps function and the value indicated in the method is "overlaps" as the latter method uses the overlap package to split migration period.
the calculated data.
A boolean which indicates, in the case of glass eel, that the function fun_weight_conversion has been run to convert the weights to numbers using the weight to number coefficients in the database (see report_ge_weight).
A parameter indicating if negative migration (downstream in the case of upstream migration devices) have been converted to positive numbers, not developed yet
