Position-velocity cuts across L 1622, as marked in Fig. 8. Top: cut along the clouds major axis, starting from 5^h53^m41.^s7, 1°36′24′′ to the south-west of the cloud, ending at 5^h55^m36.^s3, 1°57′37′′ in the north-eastern corner of the mapped area. Middle row: cuts along the minor axis of the cloud; left panel (pv2): starting at 5^h 54^m19.^s9, 1°35′45′′ (south-west), ending at 5^h53^m44^s, 1°45′29′′ (north-east); right panel (pv3): starting at 5^h54^m23.^s5, 1°36′07′′ (south-west), ending at 5^h54^m23.^s5, 1°36′07′′ (north-east). Bottom row: cuts along the minor axis of the cloud, further east in the tail of the cloud; left panel (pv4): starting at 5^h 55^m11.^s5, 1°37′54′′ (south-west), ending at 5^h53^m54.^s2, 1°54′02′′ (north-east); right panel (pv5): starting at 5^h53^m54.^s2 1°54′02′′ (south-west), ending at 5^h53^m54.^s2 1°54′02′′ (north-east).
