1) The monitored values are recorded permanently (default monitoring method).
2) The items in brackets refer to SM2R1 statistics, not report groups.
3) The monitored values are recorded permanently for channels (default monitoring method).
4) The data is available online via the SM2GDAT program interface or in the output file (analysis only possible using ANALZYER)
