¹³CO (top) and C¹⁸O (bottom) moment zero maps. The contours are drawn at intervals of 10% of the peak starting from 5σ. The continuum position is indicated by the green stars and the arrows show the direction of the red and blue-shifted outflow components taken from the literature (TMC1: 0°; TMR1: 165°; TMC1A: 155°; L1536: None Ohashi et al. 1997a; Hogerheijde et al. 1998; Brown & Chandler 1999). The bottom row show C¹⁸O integrated flux maps from the velocity unresolved spectra (typically 1–2 channels) taken within the WideX with contours of 10% of the peak starting from 3σ (~30 mJy beam^-1 km s^-1). The zero moment maps are obtained by integrating over the velocity ranges [υ_min,υ_max]  =  [−3, 11] ,    [−1, 11] ,    [−2, 12] ,    [−2, 12] for TMC1A, TMC1, TMR1, and L1536, respectively.
