NAME

       rivet-rescale - Rescale histos in observable-file of AIDAFILE to the area of the corresponding histos in REFDATAPATH

SYNOPSIS

       rivet-rescale [-r <REFDATAPATH>] [-O <observable-file>] [-b <bindef> [-b ...]] <AIDAFILE> [<OUTFILE>]

DESCRIPTION

       Rescale	histos	in  observable-file of AIDAFILE to the area of the corresponding histos in REFDATAPATH. REFDATAPATH can either be a single
       AIDA-file or a directory containing AIDA-files. By default the standard Rivet reference files are used.

       Observable definitions of the form /CDF_2000_S4155203/d01-x01-y01  1.0 can be used to specify an absolute normalisation (1.0, here)  for  a
       histogram rather than using the reference histo. If the --multiply switch is used, the ref histo area will be scaled by the given factor to
       give the target normalisation.

       You can also define bins to chop out in the observable-file in the same way as in chop_bins: /CDF_2000_S4155203/d01-x01-y01:0:35  1.0  This
       will chop the bins with Z-pT > 35 GeV and obtain a rescaling factor from that restricted bin range: note that the output histograms will be
       rescaled but *unchopped*.

       Only one bin definition can be used for each histogram, so the last bindef specified for that histo path will be the one which is  applied.
       The bindefs are constructed in order from those in the obsfile, and then those given on the command line with the -b flag, like this:

       -b "/CDF_2000_S4155203/d01-x01-y01:5:135 2.0"

OPTIONS

       -h, --help
	      show this help message and exit

       -O OBSFILE, --obsfile=OBSFILE
	      Specify a file with histograms (and bin ranges) that are to be normalised.

       -b BINRANGES, --bins=BINRANGES
	      Specify a histogram and bin range that is to be used.  The format is `AIDAPATH:start:stop'.

       -r REFDIR, --refdir=REFDIR
	      File of folder with reference histos

       -a     Produce AIDA output rather than FLAT

       -f     Produce FLAT output rather than AIDA

       --multiply
	      Rescale histos using weight given as factor rather than new area

       -i, --in-place
	      Overwrite input file rather than making inputrescaled.aida

       --fast Try loading only reference files from refpath that match analyses in input-file

EXAMPLES

       rivet-rescale out.aida
	      This will return the histos in out.aida, scaled to match the overall normalisations of the Rivet ref data.

       rivet-rescale -O observables.obs out.aida
	      This  will  return  the histos in out.aida, scaled by the bin definitions specified in observables.obs (and using the Rivet ref data
	      again)

       rivet-rescale -r path/to/CDF_2000_S4155203.aida -b "/CDF_2000_S4155203/d01-x01-y01:2:5" out.aida
	      For this Z-boson pT-distribution, the normalisation to the provided ref data file is only applied between 2 < x < 5 GeV.

NAME

       histo - compute 1-dimensional histogram of N data columns

SYNOPSIS

       histo [-c][-p] xmin xmax nbins
       histo [-c][-p] imin imax

DESCRIPTION

       Histo  bins columnular data on the standard input between the given minimum and maximum values.	If three command line arguments are given,
       the third is taken as the number of data bins between the first two real numbers.  If only two arguments are given, they are  both  assumed
       to be integers, and the number of data bins will be equal to their difference plus one.	The bins are always of equal size.

       The  output is N+1 columns of data (for N columns input), where the first column is the centroid of each division, and each row corresponds
       to the frequencies for each column around that value.

       If the -c option is present, then histo computes the cumulative histogram for each column instead of the straight frequencies.	The  upper
       value  of  each	bin  is printed also instead of the centroid.  This may be useful in computing percentiles, for example.  Values below the
       minimum specified are still counted in the cumulative total.

       The -p option tells histo to report the percentage of the total number of input lines rather than the absolute counts.  In the  case  of  a
       cumulative total, this yields the percentile values directly.  Values above the maximum are counted as well as values below in this case.

       All  input data is interpreted as real values, and columns must be white-space separated.  If any value is less than the minimum or greater
       than the maximum, it will be ignored unless the -c option is specified.

EXAMPLE

       To count data values between -1 and 1 in 50 bins:

	 histo -1 1 50 < input.dat

       To count frequencies of integers between 0 and 255:

	 histo 0 255 < input.dat
