The Histogrammer Instrument

Takes eventfile input (Virtual_input/Vitess/MCNP/Tripoli4/MCPL formats) and applies Monitor_nD to generate histograms. Histograms can be chosen freely using the options string, see mcdoc Monitor_nD.comp

Description

Takes any possible  McStas eventfile inputs (Virtual_input/Vitess/MCNP/Tripoli4 formats) and applies
Monitor_nD to generate user-selectable neutron histograms.

The 'options' parameter allows to customize the type of histogram to generate.
We suggest:
"sphere theta phi outgoing previous" (this is the default)
"previous, multiple, auto, x, y, z, vx, vy, vz, hdiv, vdiv, tof, lambda"
"previous, auto, x, y"
"previous, auto, tof, lambda"

Example: mcrun Histogrammer.instr MODE=0
- Gives information on the input parameters

Example: mcrun Histogrammer.instr filename="events.dat" MODE=1 options="sphere theta phi outgoing previous"
- Reads a Virtual_output generated event file and applies a spherical PSD

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
filename	string	Specifies input event file	0
MODE	int	Input file mode/format - 0 for help on usage 1=McStas,2=Vitess,3=MCNP,4=Tripoli4,5=MCPL	0
options	string	Specifies the histogramming rules used by Monitor_nD.	"sphere theta phi outgoing previous"
bufsize	int	Vitess_input 'buffersize' parameter - see mcdoc Vitess_input	10000
xwidth	m	Horizontal width of detector, or diameter for banana,cylinder and shpere geometry	0.1
yheight	m	Vertical height of detector, for plate, cylinder, banana shape	0.1
