# --- Example shell for refRealHTI.c
# --- real reflection coefficients
# --- for interfaces between two HTI
# --- media with throughgoing symmetry
# --- planes. Coefficients can be computed
# --- at arbitrary azimuthal direction

# --- Input parameters are Thomsen parameters
# --- (i.e., anisotropy parameters defined 
# --- with respect to the symmetry axis)
