 A python function has been created in order to access the ''SPECS-EUPORIAS Data Portal'' in a user-friendly way, allowing the retrieval of dimensional slices of selected simulation members from the ECMWF's SYSTEM4 model. This function ([browser:software/specseuporias/dataserver/python/load_system4.py load_system4.py]) automatically cares about the proper location of the right indices for data sub-setting across the different variable dimensions, given a few simple arguments for subset definition. In addition, instead of retrieving a NetCDF file that needs to be opened and read, the requested data is directly loaded into the current python working session, according to a particular structure described below, prior to data analysis and/or representation.

 * `members`: List of members to select. In the above case, a single member (the first) of the System4 ensemble is loaded, but additional members could be also specified  (e.g. `members=[0,1,2,3,4]` for the first five members). 
-* `lonLim`: Vector of length = 2, with minimum and maximum longitude coordinates, in decimal degrees, of the bounding box selected.

 * `season`: A vector of integers specifying the desired season (in months, January=1, etc.) of analysis. Options include a single month (as in the above example) or a standard season (e.g. `season = [12,1,2]` for standard Boreal winter, DJF).
 * `year`: List of years to select. Note that in cases with year-crossing seasons (e.g. winter DJF, `season = [12,1,2]`, for a particular year period `year = [1981,1982,1983]`), by convention the first season would be DJF 1981/82.
