Baselines and position angle (projected on the sky) are given as the mean for the observation. a The first standard star observation on run D1 (of HD61935) showed great variation in visibility with wavelength (see Sect. 2.4), and so this was rejected as a suitable observation for calibration; b during run A the observation of standard star HD73840 could not be used, as the telescope beams showed poor alignment on the readout array. Thus the observation of HD69830 was calibrated with HD61935 only, since the next usable observation of a standard (HD116870) was taken much later in the night after sky conditions had changedsignificantly.
