Respected sir

Thank you for your kind help. The information is very useful for me.

I want to ask one more question that which option of flair i will

use to calculate the y axis result in (cm-2 per incident particle)

unit. Just i want to remove the per GeV and per Sr terms or how i

will do it manually.

waiting for your reply

Thanking you in advance.

*> Dear Bhushan,
*

*>
*

*> From the manual:
*

*> "Note: The results of a USRBDX boundary crossing estimator are
*

*> always given as DOUBLE DIFFERENTIAL distributions of
*

*> fluence (or current) in energy and solid angle, in units
*

*> of cm-2 GeV-1 sr-1 per incident primary, EVEN WHEN ONLY
*

*> 1 INTERVAL (BIN) HAS BEEN REQUESTED, which is often
*

*> the case for angular distributions."
*

*> The output of the USRBDX card is fluence. Now if you do what you are
*

*> asking "multiply by the difference of the Ist and IInd column" what you
*

*> will get is a histogram of weighted counts for every energy bin.
*

*> For flair please look in the last fluka courses the flair-2.pdf file.
*

*> You have several options depending on what you will like to plot, both
*

*> on the X-axis and the Y-axis.
*

*> Variables: "Low" xl = Ist column, "High" xh = IInd column, Y = IIIrd
*

*> column
*

*>
*

*> X-axis
*

*> 1. GeoMean: sqrt(xl*xh) <Xgeo>
*

*> The geometrical mean of the two values. Useful if you want to plot
*

*> point in the geometrical center of each bin. To be used only if you make
*

*> a logX plot. Be careful this is only for plotting it doesn't care what
*

*> you have scored in fluka linear or log in energy.
*

*> 2. Mean (xl+xh)/2 <X>
*

*> Normal mean. To be used for linear plots
*

*> 3. Low (xl)
*

*> Low value of the bin. To be used when plotting like a histogram the
*

*> data, together with the "steps" style
*

*> 4. High (xh)
*

*> High value of the bin. Same as 3 but for "histeps"
*

*>
*

*> Y-axis
*

*> There you have several choices on the way you want to represent your data
*

*> i) Y
*

*> The value of the IIIrd column as given by fluka
*

*> ii) Y x <X>
*

*> The value multiplied by the mean of the first two columns. To plot in
*

*> isolethargic way with linear x-axis
*

*> iii) Y x <Xgeo>
*

*> Multiplied by the geometric mean. Isolethargic way with log x-axis
*

*> iv) Y x Xl
*

*> ...
*

*> v) Y x Xh
*

*> ...
*

*> vi) Y x DX
*

*> Number of "counts" per bin.
*

*>
*

*> Examples:
*

*> * To plot normal fluence like a histogram (log or linear) you have to
*

*> choose
*

*> X: Low [xl]
*

*> Y: Y
*

*> With: steps
*

*>
*

*> * To plot normal fluence with error bars (linear)
*

*> X: Mean (xl+xh)/2
*

*> Y: Y
*

*> With: errorbars
*

*>
*

*> * To plot normal fluence with error bars (log)
*

*> X: GeoMean sqrt(xl*xh)
*

*> Y: Y
*

*> With: errorbars
*

*>
*

*> * To plot isolethargic fluence as histogram (log)
*

*> X: Low [xl]
*

*> Y: X*<Ygeo>
*

*> With: steps
*

*>
*

*> ...
