[ascl:2404.013] Meanoffset: Photometric image alignment with row and column means

Meanoffset performs astronomical image alignment. The code uses the means of the rows and columns of an original image for alignment and finds the optimal offset corresponding to the maximum similarity by comparing different offsets between images. The similarity is evaluated by the standard deviation of the quotient divided by the means. The code is fast and robust.
