## Release note
***v4.3*** Feb. 6, 2025: The directory for the out-of-core files of the sensitivity matrix becomes changeable.
***v4.2*** Mar. 25, 2024: I modified some parts to allow the use of large-scale models and large datasets.
***v4.1*** Nov. 9, 2021: This new version supports difference filter. The error calculation of log10(apparent resistivity) is modified. Rotation angles of distortion matrix are limited to from -90 to 90 (deg.) when gains and rotations of galvanic distortion are estimated.
