摘要：
ESO will measure pressure fluctuations on the surface of the 76 m radio telescope at Jodrell bank and on a scaled down model of this telescope in a wind tunnel. The data will be used to calculate the effect of pressure variations on the overall deformation of the mirror and in particular the effect on segment to segment misalignments taking into account the correction capabilities of the segment supports.
