1. Backends Available with CIMA
Different backends are supported by CIMA depending on the selected receiver and observation type (spectral line or pulsar). CIMA has traditionally supported two backends: the interim correlator for spectral line single-pixel receiver observations and the WAPPs for any kind of observation. The WAPPs behave quite differently in spectral line and in pulsar mode, with the differences being so big that the observer has to select which type of obsercvation already at start-up of CIMA. ...
