\caption{Details of the observations used for this work. $N$ is
  the number of exposures that were taken with a given detector
  integration time (DIT). NDIT denotes the number of integrations that
  were averaged online by the read-out electronics during the
  observation. The scale of all observed images is 0.027$^{\prime\prime}$ per pixel.}
