Abstract:
We have developed further the technique of time-dependent modelling of
magnetohydrodynamic shock waves, with a view to interpreting the
molecular line emission from outflow sources. The extensively observed
source L1157 B1 was chosen as an exemplar of the application of this
technique.

Global notes:
Note (G1): The levels are identified by the quantum numbers separated by
an underscore (_): JK+K- where J is the rotational quantum number
and K is its projection on the symmetry axis of the molecule; the '+'
and '-' subscripts refer to the oblate and prolate symmetric top
limits, respectively.
