The beam contours are in uplink G/T (uplink gain to noise temperature ratio). This refers to the uplink receive beam into the satellite and you should use this number in the uplink part of the link budget calculation. Additional information you need is the uplink power flux density required, per transponder to achieve saturation (single carrier per transponder, or to achieve the nominal input back off required for multi-carrier operation. The figure may be adjusted using on board gain step adjustments. You also need the corresponding downlink eirp map.
