OCOEFF

Specifies the coefficients of the polynomial function which determines the line number in the input radar image, given the distance along the flight path in metres from OPOINT. This parameter must be calculated by the FLIGHT program.

Coefficients a,b,c,d,e,f,g,h,i are assigned in ascending order:

     L = a + (b * D   ) + (c * D**2) + (d * D**3) + (e * D**4)
           + (f * D**5) + (g * D**6) + (h * D**7) + (i * D**8)

D is the distance in metres from OPOINT, and L is the input radar image line number. D can be positive or negative, depending on whether the input line number is ahead of or behind the coordinates specified by OPOINT.
