Status:

base class, extends NXobject

Description:

Container for reporting a set of annular dark field images.

Symbols:

n_images: Number of images

n_y: Number of pixel per image in the slow direction

n_x: Number of pixel per image in the fast direction

Groups cited:

NXdata, NXprocess

Structure:

PROCESS: (optional) NXprocess

Details about how the images were processed from the detector readings.

program: (optional) NX_CHAR

Commercial or otherwise given name to the program which was used to process detector data into the adf image(s).

@version: (optional) NX_CHAR

Program version plus build number, commit hash, or description of an ever persistent resource where the source code of the program and build instructions can be found so that the program can be configured in such a manner that the result file is ideally recreatable yielding the same results.

adf_inner_half_angle: (optional) NX_FLOAT {units=NX_ANGLE}

Annulus inner half angle

adf_outer_half_angle: (optional) NX_FLOAT {units=NX_ANGLE}

Annulus outer half angle

DATA: (optional) NXdata

Annular dark field images.

@long_name: (optional) NX_CHAR

Image intensities

intensity: (optional) NX_NUMBER (Rank: 3, Dimensions: [n_images, n_y, n_x]) {units=NX_UNITLESS}

Image intensity values.

image_id: (optional) NX_UINT (Rank: 1, Dimensions: [n_images]) {units=NX_UNITLESS}

Image identifier

@long_name: (optional) NX_CHAR

Image ID.

ypos: (optional) NX_NUMBER (Rank: 1, Dimensions: [n_y]) {units=NX_LENGTH}

Pixel center of mass position y-coordinates.

@long_name: (optional) NX_CHAR

Label for the y axis.

xpos: (optional) NX_NUMBER (Rank: 1, Dimensions: [n_x]) {units=NX_LENGTH}

Pixel center of mass position x-coordinates.

@long_name: (optional) NX_CHAR

Label for the x axis.
