Dear Abhishek,

"but what paul has done is Mr. karas and i said interpolation."

I dont think so. Mr Paul has managed to get an equation wherein if I plug the MM value I will directly get the Deg value based on the provided pattern.

Kindly recheck Mr Pauls posting again.

Or maybe I am missing something of what you are trying to convey.

( Incidentally the table has been " turned inside out " and I now have the Deg values for all MM values from start to finsih at 1mm intervals. ANd the problem stands solved with the LUT.)

Thanks - all you members.
