 +As some variables of this namelist can be related to another namelist (i.e. the variable "Field_Recording_Rate" of this namelist is bounded to the namelist "Instantaneous_Fields_Listing", see further for more details), it could be useful to split this data in several parts in order to group the same class of data (see the example here).

The physical quantities bounded to the probe time-series are defined with the namelist "Probe_Quantities_Enabled". For instance, when "Probe_Recording_Rate=10", a new value is added to probe time-series for all time iteration numbers that are a multiple of 10).
