Zoom of the integrated intensity map toward Cond-2, -3 and the protostar, with the ∇v_LSR vector orientations from Fig. 9 shown with white lines. The black line at the top represents a gradient magnitude of 10 km s⁻¹ pc⁻¹. The black star indicates the position of B5-IRS1. The white ellipse in the bottom left corner represents the beam size. Black dashed contours outline the NH₃ filaments (P15; S21). Black solid contours outline the edges of the condensations (P15). The red circle at the top left corner represents the area used to calculate the gradients. The scale bar at the bottom right marks a length of 1000 au.
