Does anyone know if it is possible to access the raw data that is used

it was an interpolation of the classical FD text data. But then I
realized that the graphical plots have a finer time increment than the
FD text data. It is quite possible that they might be interpolating in
space and time, but I would like to know if there is another data set
that I am not aware of.
