    ----- mode -----
    0: Fourier shell correlation.
    1: Fourier shell phase residual.
    +2: Correlation between L and H
    +4: Without equator.
    ----- mode 2 -----
    0: Correlation between same size images
    1: Correlation between 2D image and image extracted from 3D image.
    +2: Correlation between 2D different size images. In1 is compared with center of In2.
