The pdev spectrometer dshift parameter (see layout of spectrometer scaling ) down shifts the output of the power computation before accumulating the spectral values in the 40 bit accumulators. ... As an example: a 1 second integrations at 170 MHz with: (A/D=48,pshift=0x1555, dshift=0,ashift=0) has LO feedthrough birdies close to 1.5e9. The maximum allowed value is 4e9. ... The allowable range for dshift had been computed from the spectral mean with dshift = 0 (see page 2 of the plots) . ...

... S _t_c,f_c,(_t),c = . ... We refer to ( 10 ) as the ``Gaussian chirplet transform'' (GCT). One characteristic of the one-dimensional Gaussian window is that its TF energy distribution is a bi-variate Gaussian function. Therefore its TF energy countours are elliptical, so shearing the TF distribution along the time axis provides no new degrees of freedom that cannot be obtained by combinations of shearing along the frequency axis together with dilation. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ...
