C
C  PURPOSE:   Examines the collison strengths of adf04 files for any 
C             discrepencies, outlyiny points, mistakes etc.
C
C             Three methods are used for checking
C               o  fit a minmax polynominal and flag excessive errors
C               o  find large deviations from a 3-point running average
C               o  find excessive changes in slope
C
C             The first method really checks for smoothness with the
C             second looking for outlying points. (The minmax fit
C             should also spot these). The third is not so successful
C             and care should be taken in using it.
C
C             All collisions and temperatures are transformed by the
C             Burgess-Tully method before the tests are applied.
C
C             Based on off-line test_adf04.for code (Martin O'Mullane,
C             16-2-99).
