%X <p>Raw microscopy data underlying the publication, structured per experiment (figure). The imaging setting that is varied in the experiments (exposure/dwell time, beam current, landing energy) is indicated by the folder or image name. The images may have a data bar indicating the relevant acquisition settings.</p><ul><li>For more information on the sample preparation and image acquisition, see the Methodology section in the publication.</li><li>The code and data analysis notebooks are included in the accompanying Github repository: https://github.com/hoogenboom-group/Kievits-OSTEM-2023</li></ul><p><br></p><p>Data set structure:</p><ul><li><strong>1_Optimization-OSTEM</strong>: contains the images for the landing energy optimization (Figure 2 in the article). Images have a pixel size of 1 nm and where acquired with increments of 500 eV (electron volts). Dwell times are indicated in the folder names. The 'Qualitative' folder contains a subset of these data for ease of plotting Figure 2A.</li><li><strong>2_Qualitative-comparison</strong>: contains qualitative images of rat pancreas and zebrafish larva (Figure 3). Both raw images (with metadata in TIFF header) and cropped images are included (used for publication). Images have a pixel size of 4 nm.</li><li><strong>3_SNR-comparison-detectors: </strong>contains images used for the quantitative comparison of detectors (Figure 4). Contains a folder per detection technique with all the images. The 'Qualitative' folder contains a subset of these data for ease of plotting Figure 4A.</li><li><strong>4_Image-resolution-detectors</strong>: contains raw images and extracted edge widths from FEI Image (Figure 5). The acquisition settings are indicated in the folder names, with one folder per detection technique.</li><li><strong>5_Current-SNR-relation: </strong>contains the images with increasing beam current / fixed dwell time and increasing dwell time / fixed current (Figure 6). The 'Qualitative' folder contains a subset of the data for ease of plotting Figure 6A and 6B.</li><li><strong>6_Supplementary</strong>: contains the supplementary data, used for the background texture analysis.
