Edge-on view of G332.83-0.55. The calculated gas structure is in red, and all external material apart from the calculated structure is in blue. (a) The gas distribution in G332.83-0.55 can be everywhere. (b) In 2D computation, all molecular gases are assumed to be concentrated on the same plane. Thus, we obtained a maximal estimate for the tidal strength. (c) Taking a characteristic scale height of the molecular gas as 0.03 pc, all external material apart from the calculated structure were moved vertically to 0.03 pc away. Thus we obtained a minimal estimate of the tidal strength.
