Hello
could you please help me understand the output of different
scoring cards ?
I am interested in the number of particles from target.
I use the example from tutorial course.
example : ... let us calculate the output of CHARGE Hadrons
1) from USRBDX card (unit 50) the output of Charge Had into AIR :
-----------
Sp3ChH :
Tot. resp. (Part/cmq/pr) 4.5073396E-03 +/- 1.239388 %
( --> (Part/pr) 1.486836 +/- 1.239388 % )
and I can get cumulative value :
5.5792654E-05 = 5.4125518E-05 * (5.011875 - 3.981074 )
... ok ...
2) from URSYIELD card (unit 57) the output of CHARGE Hadrons :
-------------
YieAng2 :
Detector n: 2 YieAng2
(User norm: 1.00000000
sigma: 1.00000000 mb
distr. scored: 218 ,
from reg. 4 to reg. 5 )
linear 1st variable (x1) binning from 0.0000E+00 to 3.1416E+00
18 bins ( 1.7453E-01 wide)
2nd variable (x2) ranges from 0.0000E+00 to 1.0000E+01
1st variable (x1) is: Laboratory Angle (radians)
2nd variable (x2) is: Laboratory Kinetic Energy
The scored double differential yield is (normalized per primary
particle):
plain d2 N / d x1 d x2 where x1, x2 are
the first and second variables
1st variable (x1) differential is a solid angle one
Tot. response (integrated over x1) 0.1308400 +/- 1.208114 %
( --> Tot. response without normaliz. 0.1308400 +/-
1.208114 % )
... the total number is 0.1308400
for energy interval - 10 GeV :
total number = 0.1308400 * 10 = 1.308400
so, we have difference with initial value: 1.486836
... and I cannot get cumulative distribution here :
for the 1-st value :
4.3209166E-05 * 0.1745329 = 7.54142104856139949e-06
but in the output I see :
2.0000010E-05
---------------------
so, I have the following questions:
*) integral for charge hadrons are different for
USRBDX and URSYIELD cards : 1.486836 and 1.308400
*) and for the distribution I cannot get cumulative values in
URSYIELD card output
*) how to connect total number of charged hadrons from
USRBDX card : 1.486836
with Integral from USRBIN card : 1.68 (from plot)
---------------------------
thank you,
Vladimir
