Displaying And Navigating

Opening the Instrument View

To see the Instrument View

1. Load a data set, such as MUSR00015189

2. As this is a WorkspaceGroup, reveal the contained workspaces by clicking on the small triangle

3. Right-click on the workspace named MUSR0001589_1 in the Workspaces Toolbox and select “Show Instrument”

Different projections

There are two ways to display the instrument geometry: the Full 3D view and an “unwrapped” view. An “unwrapped” view shows a projection of the instrument onto a surface (a cylinder or a sphere) unfolded onto the screen. Use this drop-down menu to select the type of the projection

Here is an example of how an instrument may look in different views:

Settings

Some aspects of the instrument appearance in the view can be set from the Display Settings drop-down menu.

Navigating in 3D

In the 3D view:

• The X axis is red.

• The Y axis is green.

• The Z axis is blue.

In most cases, the Z axis is the direction of the incident beam, but not for every instrument!

Rotate the instrument by left-clicking and dragging.

Pan the view by right-clicking and dragging.

Zoom in and out by scrolling or holding down the middle button and dragging up and down.

Zooming in 2D

In an unwrapped view (such as cylindrical) to zoom in select an area by left-clicking and dragging.

Right click to zoom out.
