Abstract
We analyse the influence of gravitational lensing on some statistical descriptors of the texture of the CMB data. Those quantities depend on the coherence angle of the temperature fluctuations, for which we pre sent calculations. The result of gravitational lensing is a decrease i n the coherence angle for popular models of galaxy formation. As a con sequence the statistical descriptors studied could be increased by a 7 0% for present experiments operating at arcmin scales.
