Amplitude in Jy versus the projected baseline showing the combination of the interferometer and single-dish data, from the upper sideband (top) to lower sideband (bottom). Red and blue dots present data from the SMA on Feb. 15, 2005 and Feb. 19, 2005, respectively, showing the lack of baselines shorter than 10 kλ. Black dots are data converted from 30 m single-dish observations, which fill in the missing short spacing information.
