Peak intensity, first moment (centroid velocity), and second moment (translated to FWHM) of the lines of ¹³CO 1−0 (colors) and [C ii] contours. The black marks indicate the positions of IRS 1-3. The contour levels for the [C ii] peak intensity match those from Fig. 2; for the line position they are given at −9.5, −8.5, −7.5, and −6.5 km s^-1, and for the line width at 3, 4, 5, and 6 km s^-1. Velocities are given in LSR (local standard of rest) and intensities in main beam temperatures.
