real [1.] determines the magnitude of the spike. Crossing spikes add their magnitudes.
[1] number of surfaces
[n1/2] - static shift
[0] what to scale the 2nd axis by (b2*(o2+d2*i2))
[0] what to scale the 3rd axis by (b3*(o3+d3*i3))
[0] what to scale the 2nd axis by (c2*(o2+d2*i2)^2)
[0] what to scale the 3rd axis by (c3*(o3+d3*i3)^3)
[o2] minimum extent along extent
[o3] minimum extent along extent

[1] Add crossing surfaces (1) or replace value (0)
[0] If 1, perform causal integration
['sec'],['km],['km'] standard seplib meaning
Make linear and parolbic surfaces. Spikes are placed at nearest integer location corresponding to the formula:
iz=floor(((a+b2*(o2+d2*i2)+b3*(o3+d3*i3)+ c2*(o2+d2*i2)^2 + c3*(o3+d3*i3)^2)-o1)/d1+.5)
