Fluctuations of water vapour content in the troposphere are one of the worst enemies of millimeter/submillimeter aperture synthesis observations, being responsible of loss of coherence in the radio signal and limiting the spatial resolution. The use of the fast switching technique tries to minimize this effect through fast and succesive cycles between calibrator and source. Here we present fast-switching tests in millimeter/submillimeter wavelengths carried out at the Submillimeter Array (SMA)doi:10.1007/978-3-642-11250-8_153 fatcat:5g6dlkjcordppkp7v6mbbh57be
