We present the AMR/RJET hydrodynamical simulations of a plane-parallel
pressure-matched relativistic jets evolving in the medium with
exponential distribution of the density, exp(-y/H), for H=20 (H=2 or
H=5 for high-resolution models).
The computational domain of size (x,y)=(200x200) was covered by base
grid with resolution of (100x100) zones and at low resolution we used
one level of refinement by a factor of 4 in each direction (resolution
of 2 zones per beam radius). High-resolution models were obtained on
base grid 40x60 zones and two levels of refinements (16 zones per beam
radius).
All calculations were done with the CFL number of 0.4 and adiabatic
exponent Gamma=5/3.

Low-resolution models
2 zones/Rb, 2 levels, (100x4):(100x4), 400x400
same as exp_std but with exponential stratification of density and ang=45
same as exp_exp but for Mb=10
same as exp_exp but for gamma=12
same as exp_exp but for Eta=1
same as exp_exp but gamma=3 and Eta=0.02
same as exp_exp but grid twice as large; two levels of refinements
High-resolution models
16 zones/R_b, 3 levels, (40x4x4):(60x4x4), 640x960
