Column density maps for MWISP ^13^CO mol. clouds

We have obtained column density maps for an unbiased sample of 120 molecular clouds in the third quadrant of the Milky Way midplane (b<=|5|{deg}) within the Galactic...我们针对银道面（Milky Way midplane）第三象限内银纬|b|≤5°的120个分子云（molecular clouds）无偏样本，获取了其柱密度图（column density map），该样本位于银河……范围内。
