Notes.

^(a)

Number of exposures.

^(b)

Detector integration time. The total integration time of each observation amounts to N× DIT.

^(c)

The pixel scale of the NACO S27 camera is 0.027″/pixel, that of S13 is 0.013′′/pixel.

^(d)

Used for proper motion measurements.

^(e)

Imaging observations used to investigate the structure of the bow shocks.

^(f)

SAM observations used to investigate the structure of the bow shocks.
