Very simple question on detection significance

  1. Aug 18, 2010 #1
    Hi all,

    At this website:
    http://heasarc.gsfc.nasa.gov/docs/swift/analysis/threads/uvot_thread_afterglows.html" [Broken]

    The passage at the bottom states that a V-band magnitude of 17.62, with an error ± 0.02 is a 49.4-sigma detection significance.

    How is this value calculated? Could you provide the working? I have a similar problem and would like to know at what magnitude limit I can claim a statistically significant (6-sigma) detection.

    Thanks,

    d
