Description

Simulated transmission images of a hopfion for testing MARTApp, an application developed in ALBA Synchrotron for the analysis and reconstruction of magnetic tomographies performed at BL09 MISTRAL beamline.

The dataset consist of two orthogonal tilt series (TS1 and TS2) and its magnetic reconstruction using MARTApp.

The transmission images of sizes 588x588 are located in the following files:
    - Hopfion_1_FFnorm_stack.hdf5: contains the transmission images for the C+ polarization, TS1.
    - Hopfion_-1_FFnorm_stack.hdf5: contains the transmission images for the C- polarization, TS1.
    - HopfionRot_1_FFnorm_stack.hdf5: contains the transmission images for the C+ polarization, TS2.
    - HopfionRot_1_FFnorm_stack.hdf5: contains the transmission images for the C- polarization, TS2.
Images are saved in the HDF5 dataset /TomoNormalized/TomoNormalized/. The dataset TomoNormalized/polarization/ refers to the polarization, being '1' to C+ and '-1' to C-. The tilt angles are located in the datasets '/TomoNormalized/rotation_angle/'.    

The recovered reconstruction using MARTApp is included in the file MagneticReconstruction_Norm.hdf5. This file contains the 3 components of the magnetization in the datasets /mx/, /my/, and /mz/. The dataset /Mask3D/ includes the mask used for registration between TS1 and TS2.
