thickness	Thickness of the material in units of X0

Note: Indices of rows and columns in the table runs from 0 to nBins-1 inclusively, where nBins is the number both of rows and columns. One should be careful while reading and storing the table from ROOT-file, because iBinX = 0 and iBinY = 0 in the TH1::SetBinContent method of usually defines the underflow bin.
