Sets the amount of storage and storage precision for binnings (single
or double).
Sets also the correspondence between rotations/translations and binnings.
WHAT(1) : sets the run-time storage precision of binnings
-1 < WHAT(1) =< 0 --> ignored
=< -1.0 --> reset the storage precision to default (double)
= xxz01 --> set the storage precision to single
= xxz00 --> set the storage to only a fraction of the required
memory, that is only xx.z percent of the required
memory for this binning is actually allocated
Default = double precision storage and full memory
allocation
WHAT(2) : associates a rotation/translation matrix
=<-1.0 --> reset the associated rotation/translation to
identity (transformation index = 0)
>= 1.0 --> associates the binning(s) indicated by
WHAT(4)...WHAT(6) to the rotation/translation
defined with number NINT(WHAT(2) by a ROT-DEFIni
card
WHAT(3) : not used
WHAT(4) = lower index bound of binnings in which the requested
storage precision and/or transformation must be applied
("From binning WHAT(4)...")
Default = 1.0
WHAT(5) = upper index bound of binnings in which the requested
storage precision and/or transformation must be applied
("...To binning WHAT(5)..."
Default = WHAT(4)WHAT(6) = step length in assigning indices ("...in steps of
WHAT(6)").
Default = 1.0
SDUM : not used
Note : 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.
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.
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 option EVENTBIN and the
relevant Note).
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 to option ROT-DEFIni).
Example 1:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+...
ROTPRBIN 85500. 0.0 0.0 2.0 6.0 2.0
* Allocate only 85.5% of the required memory to binnings 2, 4 and 6
Example 2:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+...
ROTPRBIN 10001. 0.0 0.0 3.0 5.0 0.0
* Set single storage precision for binnings 3, 4 and 5
