Measurement of Hubble constant: Non-Gaussian Errors in HST key project
  data
  Assuming the Central Limit Theorem, experimental uncertainties in any data
set are expected to follow the Gaussian distribution with zero mean. We propose
an elegant method based on Kolmogorov-Smirnov statistic to test the above; and
apply it on the measurement of Hubble constant which determines the expansion
rate of the Universe. The measurements were made using Hubble Space Telescope.
Our analysis shows that the uncertainties in the above measurement are
non-Gaussian.
