Astrophysics, simple parallax error

Click For Summary
SUMMARY

The discussion focuses on calculating parallax errors in astrophysics, specifically using the formula d = 1/p, where d represents distance and p represents parallax. The user seeks clarification on how to compute parallax with varying error percentages, such as 1% and 50%. The lack of solutions in the referenced textbook complicates the user's understanding of these calculations. The community emphasizes the importance of understanding the relationship between parallax and distance to accurately assess error margins.

PREREQUISITES
  • Understanding of parallax and its significance in astrophysics
  • Familiarity with the formula d = 1/p for calculating distance
  • Basic knowledge of error analysis and percentage calculations
  • Experience with interpreting scientific equations and concepts
NEXT STEPS
  • Research methods for calculating percentage errors in measurements
  • Explore the concept of parallax in greater detail, including its applications in astronomy
  • Learn about error propagation techniques in scientific calculations
  • Study examples of parallax measurements and their associated uncertainties
USEFUL FOR

Students in astrophysics, educators teaching parallax concepts, and anyone interested in understanding measurement errors in astronomical observations.

Homework Statement



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

Homework Equations



d = 1/p

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.
