DESCRIPTION

10       Each entry below includes the name of a parameter, its Fortran type
11       (use the obvious equivalents for C), its default value, and a short
12       description of the parameter.
13
14       ´SIG´   -   Real   -    1.
15              Value of the tension factor.
16
17       ´SL1´   -   Real   -    0.
18              The slope of the curve at the first point (see parameter SF1).
19
20       ´SLN´   -   Real   -    0.
21              The slope of the curve at the final point (see parameter SF1).
22
23       ´SF1´   -   Integer   -    3
