Maps of the Cetus (Cet), Main Taurus (TauM), South Taurus (TauS), North Taurus (TauN), Perseus (Per), and California (Cal) clouds, and of the Galactic disc background (Gal) in H icolumn density, N_HI, for a spin temperature of 400 K, and in CO intensity, W_CO. The N_HI and W_CO maps are respectively labelled HI and CO. The map labelled ff shows the intensity I_ff of free-free emission toward this region. The last subplot shows the coverage of the GALFA (dark grey) and EBHIS (light blue) H i data.
