## Description

    A divergence sensitive monitor. The counts are distributed in
    (n times m) pixels.

    Example: Divergence_monitor(nh=20, nv=20, filename="Output.pos",
    xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
    maxdiv_h=2, maxdiv_v=2)

## Input parameters

Parameters in boldface are required; the others are optional.

Name | Unit | Description | Default |
nh | 1 | Number of pixel rows | 20 |
nv | 1 | Number of pixel columns | 20 |
filename |  | Name of file in which to store the detector image text | 0 |
xmin | m | Lower x bound of detector opening | -0.05 |
xmax | m | Upper x bound of detector opening | 0.05 |
ymin | m | Lower y bound of detector opening | -0.05 |
ymax | m | Upper y bound of detector opening | 0.05 |
nowritefile | 1 | If set, monitor will skip writing to disk | 0 |
xwidth | m | Width of detector. Overrides xmin, xmax | 0 |
yheight | m | Height of detector. Overrides ymin, ymax | 0 |
maxdiv_h | degrees | Maximal vertical divergence detected | 2 |
maxdiv_v | degrees | Maximal vertical divergence detected | 2 |
restore_neutron | 1 | If set, the monitor does not influence the neutron state | 0 |
nx | 1 |  | 0 |
ny | 1 | Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane | 0 |
nz | 1 |  | 1 |

AT ( | , | , |  | ) RELATIVE |  |
