Individual channel maps of the H66α line emission, showing every channel between 40 and −39 km s^-1. The velocity of each channel is given in the upper left corner of each plot. The contour levels are at 3σ, 5σ, 10σ, 20σ, 50σ, 100σ, 200σ, and 500σ (1σ = 0.7 mJy beam^-1). The image shows the inner (1′)² of the primary beam. The 3.4″ synthesized beam is shown in the lower left corner of each channel map. A scale of 0.1 pc is shown in the lower right channel map. The (0, 0) position is at RA(J2000) = 20h 39m 02.557s and Dec(J2000) = 42d 19′ 47.2″.
