Spatial distribution of the clouds from the MD16-catalog in the (X_gal, Y_gal) plane (upper panel) and in the (R_gal, Z_gal) plane (lower panel). On the left, the MCs that overcome the detection threshold of Fermi-LAT and of an advanced detector with improved sensitivity Σ = 3 are indicated in pink and blue, respectively. On the right, the clouds visible by LHAASO after five (pink) and ten (blue) years of observations are indicated. The catalog size of the clouds is considered, and angular resolutions of 0.15° and 0.2° are assumedfor the LAT and LHAASO, respectively.
