The ìBlueî Lobe of the PV Ceph Outflow
Notes:
Looking carefully at these contours, I think the green ones to the upper right may be part of a bow shock associated with HH315C, where the blue contours form the back (redshifted side, a.k.a. ìleast blueshiftedî) and green is the front (blueshifted) part
We need to check the implications of the relative velocities of these features, under the assumptions that either they represent different episodes of ejection (in which case all velocity differences must be multiplied by a large correction for inclinatio
