Introduction
Calculate grades and tonnages using results from a Gaussian anamorphosis.
The process GAUSAN must have been run previously to create a file of the polynomial coefficients.

POLYNO |
Input file containing polynomial coefficients. This file is created as output by process GAUSAN. The following fields are required: POLYINDX - polynomial index number [0,1,2,..] COEFF - the polynomial coefficient. POLYNUM - the number of polynomials used in the transformation. |

QTN |
Output |
Yes |
Undefined |
Compulsory output file containing grade and tonnage values for different cut-offs. Change of support calculations are NOT used. It includes the following explicit fields: CUTOFF - actual cut-off grade ANAMOR - gaussian anamorphose TONABOVE - ratio of tons mined above cut-off METABOVE - ratio of metal recovered above cut-off GRDABOVE - average grade above cut-off TONBELOW - ratio of tons mined below cut-off It also includes the following implicit field. CHSUPP - change of support variable. This is always set to 1. |
