    Average per-pixel noise variance in im1, im2 respectively. Used as weighing
    of input images. Must be greater than zero.
F1, F2 : `numpy.float` > 0.
    Photometric scaling of the images. See eqs. (5)--(9)
calculateScore : `bool`, optional

Notes
-----
Calculates the centroid as if the array represented a 2D geometrical shape with
weights per cell, allowing for "negative" weights. If sum equals to exact (float) zero,
calculates centroid of absolute value array.

The geometrical center is defined as (0,0), independently of the array shape.
For an odd dimension, this is the center of the center pixel,
for an even dimension, this is between the two center pixels.

Returns
-------
ycen, xcen : `tuple` of `float`

Definition at line 470 of file zogy.py.

◆ padCenterOriginArray()

Implement also the inverse operation, crop the padding and re-center data.

Parameters
----------
A : `numpy.ndarray`
    An array to copy from.
newShape : `tuple` of `int`
    The dimensions of the resulting array. For padding, the resulting array
    must be larger than A in each dimension. For the inverse operation this
    must be the original, before padding dimensions of the array.
useInverse : bool, optional
    Selector of forward, add padding, operation (False)
    or its inverse, crop padding, operation (True).
dtype: `numpy.dtype`, optional
    Dtype of output array. Values must be implicitly castable to this type.

R : `numpy.ndarray`
    The padded or unpadded array with shape of `newShape` and dtype of ``dtype``.

Notes
-----
For odd dimensions, the splitting is rounded to
put the center pixel into the new corner origin (0,0). This is to be consistent
e.g. for a dirac delta kernel that is originally located at the center pixel.


Raises
------
ValueError : ``newShape`` dimensions must be greater than or equal to the
    dimensions of ``A`` for the forward operation and less than or equal to
    for the inverse operation.

    Two exposures warped and matched into matching pixel dimensions.

    If True (default), calculate the score image and return in ``scoreExp``.


Returns
-------
resultName : `lsst.pipe.base.Struct`

        The Zogy difference exposure (``exposure1-exposure2``).
    - ``scoreExp`` : `lsst.afw.image.Exposure` or `None`
        The Zogy significance or score (S) exposure if ``calculateScore==True``.
    - ``ftDiff`` : `lsst.pipe.base.Struct`
        Lower level return struct by `calculateFourierDiffim` with added
        fields from the task instance. For debug purposes.

Notes
-----

``diffExp`` and ``scoreExp`` always inherit their metadata from
``exposure1`` (e.g. dtype, bbox, wcs).

The score image (``S``) is defined in the ZOGY paper as the detection
statistic value at each pixel. In the ZOGY image model, the input images
have uniform variance noises and thus ``S`` has uniform per pixel
variance (though it is not scaled to 1). In Section 3.3 of the paper,
there are "corrections" defined to the score image to correct the
significance values for some deviations from the image model. The first
of these corrections is the calculation of the *variance plane* of ``S``
allowing for different per pixel variance values by following the
overall convolution operation on the pixels of the input images. ``S``
scaled (divided) by its corrected per pixel noise is referred as
``Scorr`` in the paper.

In the current implementation, ``scoreExp`` contains ``S`` in its image
plane and the calculated (non-uniform) variance plane of ``S`` in its
variance plane. ``scoreExp`` can be used directly for source detection
as a likelihood image by respecting its variance plane or can be divided
by the square root of the variance plane to scale detection significance
values into units of sigma. ``S`` should be interpreted as a detection
likelihood directly on a per-pixel basis. The calculated PSF
of ``S`` is merely an indication how much the input PSFs localize point
sources.

TODO DM-23855 : Implement further correction tags to the variance of
``scoreExp``. As of DM-25174 it is not determined how important these
further correction tags are.
