Reanalysis of the Spin Direction Distribution of Galaxy Zoo SDSS Spiral Galaxies

Table 1

The distribution of galaxies spinning clockwise and counterclockwise in the entire dataset. The values are the one-tailed binomial distribution probabilities when assuming a 0.5 probability of a galaxy to spin clockwise or counterclockwise.
