From left to right: dust emission, ¹³CO and C¹⁸O J = 3–2 integrated line emission after continuum subtraction around the binary system HD 142527. The spatial resolution is indicated by the white ellipse at the bottom-left corner of the panels. Its value is 0.′′207 ×0.′′178 for the dust emission, obtained using super-uniform weighting, and 0.′′31 × 0.′′27 for the gas emission, obtained with the Briggs parameter fixed to 0.5. The rms noise is 90 μJy beam⁻¹ for the dust emission, 5.9 mJy beam⁻¹ per channel in ¹³CO and 7.8 mJy beam⁻¹ in C¹⁸O. The integrated images for ¹³CO and C¹⁸O only take channels with a signal larger than 5 σ into account.
