Reads two columns, r(i), c(i) from file (correlation integral output of c2naive, c1, or d2) and computes local slopes by fitting straight lines. The range of the fits is specified by the option -a . For the local slope at abscissa r(i), the values c(i-a), ..., c(i+a) are used, where a is the argument to the -a option.
-o output file name, just -o means file_d
-a average using -#,...,+# (1)
-V verbosity level (0 = only fatal errors)
-h show this message
Output is to stdout, or to file file_d if -o is given.
Alternatives to local slopes are Takens' estimator c2t or to use Gaussian kernel smoothing c2g before computing slopes.
