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 \ensuremath{T_\ensuremath{\mathrm{sys}}} by \ensuremath{\overline{T}_\ensuremath{\mathrm{sys}}} in Eqs. [*], i.e.

  $\displaystyle \ensuremath{\sigma_\ensuremath{\mathrm{psw}}}^\ensuremath{\mathrm...
...h{\eta_\ensuremath{\mathrm{tel}}}\,\ensuremath{t_\ensuremath{\mathrm{tel}}}}}.
