Figure 4 Schematic representation of the relative view period with reference to the T0. The start and end time defined may be overruled if the appropriate parameters are set to true.
cycle
If cycle is specified, then the data is repeated periodically with this cycle as the period length. There is original data for only one cycle. After that cycle the dates specified in the cyclic time series the data will be repeated periodically. In other words, when cycle is defined, then a missing value is filled up with a value from the last available cycle before the missing value. Be aware that retrieveing data from a cyclic timeseries requires a relative view period to ensure that the timestamps of the array are properly set. If you retrieve a cyclic timeseries with the 'read complete forecast' readWriteMode, the array read will have timestamps that correspond to the original data.
externalForecastMaxAge
when the externalForecastMaxAge is not configured there is no maximum age for a forecast series to be used, so the returned external forcast can be very old when there is no recent forecast available. ALL external forecasts after the T0 are ALWAYS ignored. The age of an external forecast is defined as the time span between the external forecast time and T0.
