Impact on tracked observations

During tracked observations, each pixel of one polarization will look at a different position of the sky, but always the same position with time. We thus simply have to change by in Eqs. , i.e.

$$\ensuremath{\sigma_\ensuremath{\mathrm{psw}}}^\ensuremath{\... ...\mathrm{tel}}}\,\ensuremath{t_\ensuremath{\mathrm{tel}}}}}.$$ (7)
