The idea is similar to an OnOff observation, except the telescope does not move to an Off in position on the sky, but moves its intermediate frequency in frequency space. Here we call the On and Off the Sig and Ref, but both will have the signal, just shifted in the band. Since the telescope is always tracking the target, combining the Sig and a shifted (folded) Ref, a $\\sqrt{2}$ improvement in signal-to-noise can be achieved.\n",
