The input arguments in the test programs are as follows: 



a. WEDGEA = 90; the wedge angle is 90 deg. 



b. WAVEA = 135; the incident wave angle is 135 deg. 



c. XRL = 2.0 and XTH = 30; the location of the wave response 



<|> to 



be computed is at radial vector of two incident wave length dis- 

 tances and vectorial angle of 30 deg in polar coordinates. 



d. IDX = 0; the index IDX is set to 0. 

 This case is shown in Figure A2 . The outputs are given in Table Al which is 

 self-explanatory. 



5. If the location of the wave response <(> to be computed is a very 

 large distance, for example XRL greater than 18 or so, the output might print 

 the message that the number of terms is insufficient for summation in comput- 

 ing <j> . In this situation, the user must replace the integer 200 in 

 PARAMETER(NN=200), listed in Card WEDGE15 in the SUBROUTINE WEDGE list, by a 

 larger integer to ensure the accuracy.
