Cloud identification for the 3.5 km s⁻¹ component towards Cyg A. Both panels are an overplot of the dust distribution in gray (Edenhofer et al. 2024) and theoretical LSR velocities in blue and red contours (Reid et al. 2019). The largest beam of NenuFAR is marked in black dotted lines. The Sun is represented by the black cross. Top panel: overview of the sightline up to 1.25 kpc from the Sun. The gray contours correspond to the most prominent clouds in the beam of NenuFAR. Bottom panel: zoom on the close vicinity, up to 200 pc from the Sun. The purple cloud crosses the beam towards Cyg A at the expected velocity of 3.5 km s⁻¹.
