  $^{c}$~For the IOTA measurements, we used different
  detector read modes to adapt to the changing atmospheric conditions.
  The two numbers in the given 4-digit code denote the value of the {\it
    loop} and {\it read} parameter \citep{ped04} of the PICNIC camera.
  Since data taken in different readout modes is calibrated independently, the
  scattering between the data sets also resembles the typical calibration errors
  (see Fig.~\ref{fig:fitC}).\\
  $^{d}$~The dash symbol in the calibrator column
    indicates speckle measurements for which no calibrator was observed.\\
