 Warning: the present version is compiled for experiments only
 Includes coefficients for optional data inverter
 Any line beginning with a space is a comment.
 An assignment should be written without spaces.
 A space after the assignment starts a comment until the end of the line.
c_inv_n2=-0.16    inverter coefficient for i-2, default value = 0
c_inv_n1=-0.22    inverter coefficient for i-1, default value = 0
c_inv_p1=-0.10    inverter coefficient for i+1, default value = 0
c_inv_p2=-0       inverter coefficient for i+2, default value = 0
z_limit=1         inversion only if Z > limit,  default value = 1
