You were absolutely right.
We had replaced the old data set with a new one that did not contain the GCPs.
I have been trying to get this information for the last two weeks without any success so far.
I am still waiting for it and as soon as I get the new data set with all corresponding information I will publish it.
Meanwhile, I have updated the link with the old data set so every one can download and use the GCPs.
