Data for reconstruction of planar flow field with higher-order finite difference method

This is a supplementary dataset. The main dataset is found at https://doi.org/10.5281/zenodo.8199359. What is provided in the main dataset is binary data of the second velocity component v calculated by the present flow reconstruction technique with 2-point finite difference approximations to the divergence and vorticity. Meanwhile, this supplementary dataset consists of those calculated with 4-point finite difference approximations. The data format is the same as that of the main dataset. See “Synopsis.pdf” attached to the main dataset.
