If the fit keyword is not used the program prints out he values of the best fitting line. For example:

a0=0.20000000 a1=2.35000000 rms=0.6363961

Where the first two fields are the intercept and slope of the line, and the last field is the root mean square value of the difference between the data and the fit.

If fit is specified the values of the fit, and the residuals are printed to stdout.

If zc= is specified, a second term combining the data in the third column is fit.

Note: lines starting with the # character are ignored.
