The UNIVAC mainframe at Stony Brook had FORTRAN supplied by the vendor. It was almost certainly not F77 in Fall 1978.

The values of parameters are analyzed in fair detail in [math.stachexchange.com](http://math.stachexchange.com)  
Just search for brooks matelski on that site to get  
“Grid Spacing …” The cells are rectangular with aspect 5/3

Prof Laufer was a senior prof in Fall 1978. If someone was a gofer, was it a green postdoc  
or a senior prof? He had the key to the Math dept  
dumb terminal and acoustic modem which he let  
me use. The department had no output device so  
I had to hike to the computer building to retrieve  
every printout.
