ROTPRBIN
Sets the amount of storage and storage precision for binnings
(single or double). Sets also the correspondence between
rotations/translations and binnings (USRBIN or EVENTBIN), as well as
density-correction factors for user binnings (see CORRFACT).
For SDUM
= RHO-FACT:
WHAT(1)
= 0 --> ignored
< -1 --> reset the density to be used to default (that is
density correction factors for all user binnings
apart 252 (DOSE-H2O), 253 (ALPHA-D), and
254 (SQBETA-D), where dE/dx correction factors
are the default)
= 2 --> use dE/dx correction factors
= 1 --> use density correction factors for all other
processes
WHAT(2)
= not used
WHAT(3)
= not used
For all other SDUM
(see below for meaning):
WHAT(1)
= 0 --> ignored
=<-1 --> reset the storage precision to default (double)
all bins printed, always
= xxz01 --> set the storage precision to single
= xxz0y --> set the storage to only a fraction of the requi-
red memory, that is only xx.z percent of the
required memory for this binning is actually
allocated
= uxxz0y --> u > 0 makes the binning info printed only if non
zero bins exist
WHAT(2)
= 0 --> ignored
|WHAT(2)
|>100000 --> reset the associated rotation/translation to
identity (# 0)
!= 0 --> set the associated rotation/translation to
# nint(WHAT(2)
)
WHAT(3)
= 0 --> ignored
=<-1 --> reset the number of events after which EVENTBIN
results must be printed to the default (=1)
>= 1 --> number of events after which EVENTBIN results
must be printed for the binnings given by
WHAT(4-6)
SDUM
= possible index or name of a 2nd transformation associa-
ted with these binnings. Exceptionally, here SDUM
can
contain an integer number, in free format, following
any of the strings "ROT#", "Rot#", "rot#", "RO#",
"Ro#", "ro#. If any one of such strings is present, an
integer identifying the associated roto-translation is
read in the following characters. Otherwise if a name
is present, it is supposed to be the (character) name
(with sign) of the associated roto-translation. The
roto-translation order is such that the one associated
with WHAT(2)
is the innermost (first applied) one
For all SDUM
's:
WHAT(4)
= from binning "WHAT(4)
" .... (default 1).
WHAT(5)
= .... to binning "WHAT(5)
" .... (default WHAT(4)
).
WHAT(6)
= .... in step of "WHAT(6)
" (default 1).
Notes:
1) Command ROTPRBIN can be used for two different tasks, both related
to binnings requested by the user by means of EVENTBIN or USRBIN:
a) to define the precision used at run-time to store the
accumulated scores of selected binnings
b) to set the correspondence between the index of a transformation
(rotation/translation as defined by command ROT-DEFIni) and the
index of selected binnings.
2) The USRBIN/EVENTBIN output values are always in single precision,
regardless of the run-time storage precision used.
Run-time storage precision, which is double by default, should
never be changed for binnings defined by USRBIN to prevent severe
loss of data (adding small amounts in the rounding can result in
values no longer increasing with the number of primary particles).
However, this is unlikely to happen with EVENTBIN binnings, which
are reset at the end of each history.
3) In many cases, binnings defined by EVENTBIN result in a number of
sparse "hit" cells, while all other bins are empty (scoring zero).
In such cases, it is convenient to allocate less storage than
required by the whole binning structure.
In these circumstances, it may also be convenient to print to file
only the content of non-empty cells (see Note 2 to option EVENTBIN).
4) Binning space transformations (rotations and translations) are those
defined by a ROT-DEFIni card. That is, the variables used for
scoring are the primed one (x',y',z') (see the Notes 3 and 4 to
option ROT-DEFIni).
