3. NATURE OF PHYSICAL PROBLEM SOLVED

Calculates the parameters of the  cosine function that will best fit data from axial flux distribution measurements in a cylindrical reactor.
top ]
4. METHOD OF SOLUTION:  Steepest descent for the minimization.
top ]
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  Number of measured points less than 200.
top ]
6. TYPICAL RUNNING TIME

Depends on the data. A few seconds for a case  with 30 points.
top ]
7. UNUSUAL FEATURES OF THE PROGRAM

Determines the extrapolated height and estimates the associated errors for the computed quantities. When a computation has been carried out, it may be repeated after having omitted a specified number of measured points from the bottom end.
