Dear Joachim,

Thank you very much for your answer. It is true that the two usrbins are
just shifted by 10m. That was the purpose of the exersice. In my
understanding the trajectory plot is correct with respect to the axis.
And usrbin is doing what it was told to do by the ROTPRBIN card. Maybe
some expert can clarify it for us. It is the geometry plot that I cannot
Can you be a little more explicit about how to use the geometry plotter
to create a .dat file? and then overlay it in the color map? It seems to
be exactly what I want to do, but I dont know how.

Thank you,

Dear Makis

I ran your problem and also come to the conclusion that there is
something strange. However I have plotted the two trajectories on the
same graph and realize that the shifted USRBIN is the same trajectory
which has been shifted by 10 m ? I may be wrong but I would except a
different behavior from the ROTPRBIN card : that the scoring really
occurs for particle with z > 10 m not that the results (including z<10
m) be shifted by 10 m... The two trajectories should overlap exactly in
the common scoring region or am I missing something basic ?

Otherwise if you want to "force" flair to use a specific geometry
instead of using the "auto" mode for plotting URSBIN, you could still
use the geometry plotter which create a .dat file and use that file when
you plot your colour map.

In my Fluka input file, I had the need to shift a USRBIN estimator. I
did it using the ROT-DEFI and ROTPRBIN cards. But when I try to
visualize the results through the Plot feature in Flair, what I see is
that only the beam is presented according to the ROT-DEFI card. The
geometry is not shifted at all. Am I doing something wrong? Is there a
way to persuade Flair to show the geometry of the USRBIN,ROT-DEFI

In the attachements you can see that the usr22 and usr23 estimators are
the same with a shift of 10m. But if you plot them you will see that the
geometry is the second case is not shifted.

Thank you in advance,


ps. Of course ROT-DEFI's are not needed to just shift an estimator.
Shifting is the easiest example I could find to present. In reality I
want to rotate an estimator.
