Radial profile (top) and derivative (bottom) of the 13C18O(2–1) integrated intensity toward HD 163296. The derivative profile shows a clear local minimum at ∼0﹩\mathop{.}\limits^{\unicode{x02033}}﹩75, consistent with the location of the sharp CO snowline transition observed in C17O and C18O lines (C. Qi & D. J. Wilner 2024).
