Notes.

^(a)

The number of exposures N_exp, the slit width, and the exposure time T_exp are given for the three X-shooter arms UVB, VIS, and NIR separated by commas.

^(b)

The time range was derived from the start of the first exposure and the end of the last exposure of all three arms. For Set 3, it was neglected that the observations had been performed on three different nights.
