Continuum emission from G11.11P1 at 3.1 mm (filled triangles) and 1.2 mm (filled circles) in the Fourier domain. Amplitudes are averaged in bins of deprojected u-v distance from the continuum intensity peaks. The 3.1 mm u-v amplitudes have been scaled by a factor of 15. The straight solid line represents the least squares fit to the data. Error bars represent 1σ statistical errors based on the standard deviation in the mean of the data points in the bin.
