^aWe use PPV^H to denote ‘PPV|$\mathrm{_{edge}^{H}}$| and PPV|$\mathrm{_{face}^{H}}$|’.

^bWe use PPV^L to denote ‘PPV|$\mathrm{_{edge}^{L}}$| and PPV|$\mathrm{_{face}^{L}}$|’.

^cMW: Milky Way; LG: Local Group.

^dDetailed comparison of PPP^H and PPV|$\mathrm{_{face}^{H}}$| is shown in Pan et al. (2015).

^ecasa can generate the visibilities measured with ALMA, VLA, CARMA, SMA, and PdBI. ALMA is chosen for this work.
