Velocity‐integrated maps of the ¹²CO emission integrated over (a) ﹩200\leq V_{\mathrm{LSR}\,}< 210﹩, (b) ﹩210\leq V_{\mathrm{LSR}\,}< 220﹩, (c) ﹩220\leq V_{\mathrm{LSR}\,}< 230﹩, (d) ﹩230\leq V_{\mathrm{LSR}\,}< 240﹩, (e) ﹩240\leq V_{\mathrm{LSR}\,}< 250﹩, (f) ﹩250\leq V_{\mathrm{LSR}\,}< 260﹩, (g) ﹩260\leq V_{\mathrm{LSR}\,}< 270﹩, (h) ﹩270\leq V_{\mathrm{LSR}\,}< 280﹩, (i) ﹩280\leq V_{\mathrm{LSR}\,}< 290﹩, (j) ﹩290\leq V_{\mathrm{LSR}\,}< 300﹩, (k) ﹩300\leq V_{\mathrm{LSR}\,}< 310﹩, and (l) ﹩310\leq V_{\mathrm{LSR}\,}< 320﹩ km s⁻¹. The contours are from 1 K km s⁻¹ with 1 K km s⁻¹ intervals. The thin lines indicate the observed region.
