    • note
    • It is important to minimize technical noise from interference patterns in the imaging laser beam. Interference is canceled by normalization to a reference image with no atoms. To optimize the normalization, we use a relatively clean imaging beam, take the normalization image only 4 ms after the original image, and image with a cycling transition at an appropriate light level.

    • -1 is applied, where n = 5 is the filter order and f is the norm of the spatial frequency. Then the image is transformed back to real space, simultaneously increasing the image resolution by interpolation.

    • The atoms move vertically because of gravity between the two images. We separately determine the cloud center with a 2D surface fit in both pictures.

    • note
    • The correlation signal has a relative systematic uncertainty of ≈25% because of the uncertainty in measuring the absolute atom number.

    • note
    • To further optimize the signal-to-noise ratio, we have subtracted off the technical correlations that are constant over all images. These are determined by first averaging the 102 images and then calculating the remaining correlation signal.
