Synthetic proton radiographs for testing direct inversion algorithms

Proton radiographs generated by particle tracing in specified radial force profiles in cylinders and spheres saved in pradformat (github.com/phyzicist/pradformat) in a zipped folder intended as tests for direct inversion algorithms. For details see: J. R. Davies, and P. V. Heuer, https://arxiv.org/abs/2203.00495 Version 2 includes 3 additional radiographs for a spherical Gaussian potential with a reduced bin width and more bins (0.02R and 200x200 bins) Version 3 corrects an error in the x values given for the original spherical Gaussian potentials with negative mu values sphGauss_mum0p25 and sphGauss_mum0p5. The bin widths were half that of the spherical Gaussian results with positive mu values. Version 4 corrects an error in the x values given for the mesh run and adds a smoothed version of the source intensity (mu0)本数据集包含基于圆柱与球体中指定径向力分布，通过粒子追踪方法生成的质子放射影像，以pradformat格式（存储规范详见github.com/phyzicist/pradformat）存储于压缩文件夹中，用于直接反演算法的测试。详细信息可参见J. R. Davies与P. V. Heuer的研究论文：https://arxiv.org/abs/2203.00495。版本2新增了3张针对球型高斯势的质子放射影像，该势对应的分箱宽度更低且分箱数量更多（0.02R与200×200个分箱）。版本3修正了原始负μ值球型高斯势（sphGauss_mum0p25与sphGauss_mum0p5）的x轴数值错误，其分箱宽度为正μ值球型高斯结果的一半。版本4修正了网格运行任务的x轴数值错误，并新增了源强度（mu0）的平滑版本。
