Paper Abstract

We describe and illustrate the techniques used on spectrally dispersed data from the MIDI interferometer to estimate and remove variations in the atmospheric delay and dispersion. The resulting interferograms can then be added coherently yielding estimates of spectral correlated flux and differential phase. The primary advantage over incoherent estimation of correlated flux is that the system noise need not be accurately known.
