On the Measurement of the Lense-Thirring effect Using the Nodes of the   LAGEOS Satellites in reply to "On the reliability of the so-far performed   tests for measuring the Lense-Thirring effect with the LAGEOS satellites" by   L. Iorio
  In this paper, we provide a detailed description of our recent analysis and determination of the frame-dragging effect obtained using the nodes of the satellites LAGEOS and LAGEOS 2, in reply to the paper "On the reliability of the so-far performed tests for measuring the Lense-Thirring effect with the LAGEOS satellites" by L. Iorio
