Identification of velocity-coherent structures (aka fibers) within NGC 1333 in both position-position-velocity (PPV) space (panels a and b) and position-position (PP) space (panel c). The original data points are indicated by black dots. Their projection in the corresponding sub-space (either PP or PV) is indicated in grey in panels a and b. The corresponding structures identified by FIVE is colour coded in panels b and c. The main axis of each of the 14 structures found in NGC 1333 is represented by solid thick lines in panel c superposed to Herschel-Planck total column density map of Zari et al. (2016, greyscale; contours equally spaced every A_V = 5^mag). We notice that the orientation of the PPV diagrams (panels a and b) is rotated 90 deg respect to the PP maps (panel c).
