I thank A. V. Fedotov, of Russian Geophysical Company, who coded a major part of the job launcher, of the original version of the monitor, and some auxiliary programs. I appreciate the support and valuable comments by Prof. S. B. Smithson.
Some Seismic UNIX codes are modified and used in SIA:
SIA was designed to support all FORTRAN and C modules written by students of the Program for Crustal Studies of the University of Wyoming. Some of these modules were included in the system (although none of them were thoroughly tested). Thus I acknowledge the contribution of the authors of these modules.
