¹³CO derived α_{¹²CO(1 − 0)}^LTE We estimate the conversion factor under LTE assumptions using the ¹²CO(1–0) and ¹³CO(1–0) emission. We perform two iterations: (i) keeping the conditions fixed across the galaxy apart from the R_13/12 ratio and (ii) varying the ¹³CO excitation temperature,T_ex, the beam filling factor ratio, η₁₂/η₁₃, and the ¹³CO abundance between disk and center using a sigmoid function. Top three panels: variation of input parameters for α_{¹²CO(1−0)} derivation. Bottom Panel: radial Trend in . Grey points indicate measurements under fixed conditions. Red points indicate assuming a variation of the input parameters as shown in the top three panels. The blue line shows the radial trend derived from the scatter minimization technique.
