Covering $359^\\circ \\leq l \\leq 1^\\circ$ and $|b| \\leq 0.5^\\circ$ with an angular resolution of 19 arcsec, velocity resolution of 1 km s$^{-1}$, and rms $T_A^* = 0.59$ K at these resolutions, our observations unveil the complex structure of the CMZ molecular gas in improved detail. Complemented by the $^{12}$CO CHIMPS2 data, we estimate a median optical depth of $\\tau_{13} = 0.087$.
