All sorts of free low-resolution calculations can be done using the Xirio Planning Tools Application. These calculations are perfect for non profesional results or in order to adjust the station parameters before making a pay calculation. These calculations have some limitations:

•Resolution limitation of calculation according to the cartography used (MRCG).

•Storage of the calculation results in Xirio for three days, keeping only the last calculation.

To perform a free calculation the user must select the option "Free low-resolution calculation" from actions window.

A window appears, it informs about resolution and cartography layers to be used in calculations.

The MFR column (Maximum free resolution) indicates the maximum resolution allowed for calculation of free study for each cartography layer. If several cartography layers are used, the greatest of these values will be taken.

As performing payment calculations, the user can modify cartography to be used from this dialogue, updating by this way the study resolution.
