Influence of other important factors

á 

  • Use of more than one IF. When making use of different passbands, with independent receivers and amplifiers, one gains sensitivity.

  • Primary beam attenuation reduces the sensitivity for imaging in the outer regions of the field of view.

  • Polarisation measurements - important in terms of sensitivity, because measuring two orthogonal wavefronts yields a gain of a factor of for unpolarised sources. They also provide NEW information on magnetic fields.

  • Convolution and gridding in the post-observation data processing can also lead to losses.
