The primary aim of this study is to comprehensively understand the behavior of CO as an H$_2$ tracer in a low-metallicity environment ($Z\\sim0.2~Z_{\\odot}$). The total number of mosaic fields is $\\sim$8000, which results in a field coverage of 0.26$~$degree$^{2}$ ($\\sim$2.9 $\\times$10$^{5}$$~$pc$^2$), corresponding to $\\sim$10$\\%$ area of the galaxy.
