Is it possible to \input or \include data in tikz files?

I am making a contour plot, and the MWE below produces the result Is it possible to \input or \include data in tikz files?

i.e.the contour lines with value 10^{-6} and below are simply marked by 0. Did I hit some number representation limit?

\documentclass[A4]{memoir} \usepackage{tikz} \usepackage{pgfplots} \usepackage{filecontents}  \usepackage{pgfplots}  \usepackage{pgfplotstable} \pgfplotstableset{%     col sep=semicolon,     x index=0,     y index=1,     header=false }%  \begin{filecontents*}{XYZ.csv}    2016; 1;       33e-9    2016; 2;      199e-9    2016; 3;      966e-9    2016; 4;      110e-9     2015; 1;      199e-9    2015; 2;      966e-9    2015; 3;      110e-9    2015; 4;      104e-9     2014; 1;      199e-9    2014; 2;      965e-9    2014; 3;      110e-9    2014; 4;      104e-9     2006; 1;     2349e-9    2006; 2;     6528e-9    2006; 3;    18405e-9    2006; 4;    17250e-9     1993; 1;  1167453e-9    1993; 2;  2376539e-9    1993; 3;  2262076e-9    1993; 4;  2262076e-9  \end{filecontents*}  \begin{document} \begin{tikzpicture}     \begin{axis}[view = {0}{90}] ,zmode=log, log base=10 ]%         \addplot3[%             surf,shader=interp,opacity=0.8         ] table {XYZ.csv};         \addplot3[%             contour gnuplot={levels={.0000001,.000001,.00001,.0001,.001,.01,.1},draw color=black},         ] table {XYZ.csv};     \end{axis} \end{tikzpicture}  \end{document}
