Dopple shifts of binary stars

  1. Jan 24, 2008 #1
    hey guys,

    im doing a report on binary stars, using doppler shifts to get some results for periods etc but bit unsure about how to do the errors?

    i realise that the errors arise in the speed of the stars and the dispersion of the photons but how could i calculate this?

    cheers for any help

    Are you familar with the ordninary error-propagation forumula?

    yeh i know a bit about that, (dx/X)^2 and all that?
    how do i calculate the error in dispersion and that tho?
