Abstract

We present here the results of an OOF holography campaign recently performed at the SRT observing a high flux density radio source as the W3(OH) water maser by using the K-band 7 feeds Focal Plan Array receiver centered at 22.23 GHz. The resulting OOF maps (0.2 times 0.2 deg extent) of the SRT radiation pattern allowed to retrieve the gravitational large scale deformation on the aperture plane at 65 deg elevation.
