Thanks again Mats !!!
As suggested by you i did not do any removal of duplicates and used svd..results are a bit better but still there is noise. Are there any variants or alternatives of svd that I can try and see if noise reduces.

It does appear that the X values are following a curve.By noise I mean that the computed X has some errors but when I make a polynomial fit of values in X, the fit resembles the solution.
