This is Speed of Light version 3.7 Release _B_ It fixes another bug in version 3.7, so please replace SPOFLT37.ZIP and SPOLT37A.ZIP with SPOLT37B.ZIP as soon as possible. Remember, this is also a Falcon, TT, ST, and STE program, so put appropriate links in those directories as well. Thanks, Stuart Denman sdenman@cs.washington.edu
