7. Program Comments and Glossary of Terms . 



The program listing contains many comments which aid in following 

 the logic of the program. Descriptions of variables also appear where 

 they are read into the program. 



8. Run Time and Memory Size . 



BRK2D requires about 70 seconds of central processor time on the 

 CDC 6400 computer to compile and compute results for 10 different beam 

 wavelength ratios. A central memory of about 55,000 octal is required. 



9. Run and Card Deck Setup Procedures and Special Operation Instruc- 

 tions . 



In order to run the FORTRAN source program deck on the University 

 of Washington CDC 6400, the following deck is required:
