name: character. Name of the horizon object. Used to distinguish between different horizons in the model or scenario, including the automatic creation of the folder name for the model/scenario scripts.
desc: character. Description of the horizon object, for own references.
period: integer. A planning period defined as a sequence of years (arranged, without gaps) of the model planning (e.g. optimization) window. Data with years before or after the planning period can present in the model-objects and will be taken into account during interpolation of the model parameters.
