Notes.

^(a)

UTC date of beginning of night.

^(b)

Number of (dithered) exposures.

^(c)

Number of integrations that were averaged on-line by the read-out electronics.

^(d)

Detector integration time. The total integration time of each observation amounts to N × NDIT × DIT. The approximate spatial resolution of the images is 0.07″–0.10″/pixel. We refer to the different IB bands by adding the number of their central wavelength: IB200, IB206, IB224, IB230, IB233, and IB236.
