## The number of polarizations

All NOEMA antennas are equipped with dual polarization receivers. They measure the signal coming from the pointed direction in two perpendicular polarizations in the same frequency range. For the current generation of receiver (2006) and correlators, one or two polarizations are processed by the correlators, depending on the project settings. We thus have to introduce the number of polarizations , which can be set to 1 or 2 and insert it in the radiometer equation with
