Virtually the most important case is that spectra are collected in a scanning microscope (SEM or STEM) for a collection of points. The majority of cases use simple d-dimensional regular scan pattern, such as single point, line profiles, or (rectangular) surface mappings. The latter pattern is the most frequently used. For now the base class provides for scans for which the settings, binning, and energy resolution is the same for each scan point. **Symbols**: **n_images**: Number of images in the stack. **n_y**: Number of pixel per image in the slow direction. **n_x**: Number of pixel per image in the fast direction. **Groups cited**: :ref:`NXdata`, :ref:`NXprocess` .. index:: NXprocess (base class); used in base class, NXdata (base class); used in base class **Structure**: .. _/NXimage_set_em_adf/PROCESS-group: **PROCESS**: (optional) :ref:`NXprocess` Details how (HA)ADF images were processed from the detector readings. .. _/NXimage_set_em_adf/PROCESS/source-field: .. index:: source (field) **source**: (optional) :ref:`NX_CHAR ` Typically the name of the input, (vendor) file from which all the NXdata instances in this NXimage_set_em_adf were loaded during parsing to represent them in e.g. databases. .. _/NXimage_set_em_adf/PROCESS/source@version-attribute: .. index:: version (field attribute) **@version**: (optional) :ref:`NX_CHAR ` An at least as strong as SHA256 hashvalue of the dataset/file which represents the source digitally to support provenance tracking. .. _/NXimage_set_em_adf/PROCESS/program-field: .. index:: program (field) **program**: (optional) :ref:`NX_CHAR ` Commercial or otherwise given name to the program which was used to process detector data into the adf image(s). .. _/NXimage_set_em_adf/PROCESS/program@version-attribute: .. index:: version (field attribute) **@version**: (optional) :ref:`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. .. _/NXimage_set_em_adf/PROCESS/adf_inner_half_angle-field: .. index:: adf_inner_half_angle (field) **adf_inner_half_angle**: (optional) :ref:`NX_FLOAT ` {units=\ :ref:`NX_ANGLE `} Annulus inner half angle .. _/NXimage_set_em_adf/PROCESS/adf_outer_half_angle-field: .. index:: adf_outer_half_angle (field) **adf_outer_half_angle**: (optional) :ref:`NX_FLOAT ` {units=\ :ref:`NX_ANGLE `} Annulus outer half angle .. _/NXimage_set_em_adf/stack-group: **stack**: (optional) :ref:`NXdata` Annular dark field image stack. .. _/NXimage_set_em_adf/stack@long_name-attribute: .. index:: long_name (group attribute) **@long_name**: (optional) :ref:`NX_CHAR ` Image intensities .. _/NXimage_set_em_adf/stack/intensity-field: .. index:: intensity (field) **intensity**: (optional) :ref:`NX_NUMBER ` (Rank: 3, Dimensions: [n_images, n_y, n_x]) {units=\ :ref:`NX_UNITLESS `} Image intensity values. .. _/NXimage_set_em_adf/stack/image_id-field: .. index:: image_id (field) **image_id**: (optional) :ref:`NX_UINT ` (Rank: 1, Dimensions: [n_images]) {units=\ :ref:`NX_UNITLESS `} Image identifier .. _/NXimage_set_em_adf/stack/image_id@long_name-attribute: .. index:: long_name (field attribute) **@long_name**: (optional) :ref:`NX_CHAR ` Image ID. .. _/NXimage_set_em_adf/stack/ypos-field: .. index:: ypos (field) **ypos**: (optional) :ref:`NX_NUMBER ` (Rank: 1, Dimensions: [n_y]) {units=\ :ref:`NX_LENGTH `} Pixel center of mass position y-coordinates. .. _/NXimage_set_em_adf/stack/ypos@long_name-attribute: .. index:: long_name (field attribute) **@long_name**: (optional) :ref:`NX_CHAR ` Label for the y axis. .. _/NXimage_set_em_adf/stack/xpos-field: .. index:: xpos (field) **xpos**: (optional) :ref:`NX_NUMBER ` (Rank: 1, Dimensions: [n_x]) {units=\ :ref:`NX_LENGTH `} Pixel center of mass position x-coordinates. .. _/NXimage_set_em_adf/stack/xpos@long_name-attribute: .. index:: long_name (field attribute) **@long_name**: (optional) :ref:`NX_CHAR ` Label for the x axis.
