But still to make question clear.....you have values till 0.015 and you want values for 0.5,1,etc??

"Interpolation" works inside the given range of data only. If you want a point outside, this is an "extrapolation", which is instable, if you do not have additional knowledge like the wave form or the underlying formula.
