Nature of problem:This is a new version of the program and adaptation by Brandt et al. The storage requirements for a given problem have been reduced so that larger problems involving more coupled channels and higher angular momenta can be handled and some convenient new options have been provided to simplify the input and choice of phase convention. In addition we corrected an error in the calculation of the opacity function and have added a calculation of the momentum-transfer cross section. | ||

Running time:The two new test cases required 2.5 s and 34.1 s execution time, respectively, on the Cyber 74 computer. |
