Astrophysics, simple parallax error

  1. Sep 17, 2008 #1
    1. The problem statement, all variables and given/known data

    Experiment 15.2 (note this is from a book about 5 years old, and the book has no solutions!!!). I am simply unsure how to calculate between parallax with 1% error and parallax with 50% error etc. Please see the scan I done of the page: http://img210.imageshack.us/my.php?image=savevx9.jpghttp://img210.imageshack.us/my.php?image=savevx9.jpg

    2. Relevant equations

    d = 1/p

    3. The attempt at a solution

    I've tried p=1/d = 1/30 (for ground based) although how do I then account for '50%' error etc? With this book not having solutions (or even answers!) I am just getting further confused as I know these should be very simple calculations.
