The first line contains two integers: N and M. N is the number of curves in the data set, and M is the number of points in each curve). In this example, there are 4 curves and 8 points per curve.

The file contains 8 additional lines. Each of these lines contains information about one point for each. For example, the second line of the file:

-0.499 4.64E-07 4.70E-07 4.49E-07 4.52E-07

means that Curve 1 should countain the point (-0.499, 4.64E-07), curve 2 should contain the point (-0.499, 4.70E-07), curve 3 should contain the point (-0.499, 4.49E-07), and curve 4 shouldcontain the point (-0.499, 4.52E-07).
