The data uploaded here corresponds to a manuscript on x-ray /STED correlative imaging by the same authors published under the same title in Nature Communications in 2018. The provided data are subdivided into three parts: 1. The 01_STED_fig2a.mat file contains the main results shown in Fig.2a (main article) as variables: - STED_micrograph: the STED micrograph with each pixel representing single photon counts - STED_dwell_time: the dwell time at each pixel position 2. The 02_HOLO_fig2b.mat file contains the main results shown in Fig.2b (main article) as variables: - I: the emptyimage devided, but not yet filtered hologram - geo: a structure including the geometrical magnification M, the fresnel-number F, the waveguide-sample-distance z01, the sample-detector-distance z12, the effective propagation distance z_eff and the effective pixelsize dxeff - lambda: the wavelength used for all x-ray experiments - phi_raar: the reconstructed phasemap. Note, that for depicting the phase shifts, the matlab command angle(phi_raar) has to be used 3. The 03_SCANNING_fig2c.mat file contains the main results shown in Fig.2c (main article) and Fig.4 (inset) as variables: - darkfield: the x-ray dark field map of the scan area - sSAXS_dwell_time: the dwell time for each scan point - mask: the dark field mask applied on the diffraction patterns - single_diff_image: a single diffraction pattern
