XI. Other Contemporary Quad-A Results

A. Number Participants in Project Jupiter

In the initial Fall of 2002 Project Jupiter campaign there were five AAAA members that participated in the project and submitted at least partial data as of the date of this report. Most members observed and logged the separations all of the moons of Jupiter, for a total of 62 Project Jupiter observation data sets.

B. Methods Utilized

The participants used a variety of techniques to estimate the separation of the moons from Jupiter. A breakdown by method is:

Method Number of observation sets
JD Estimating 29
Sketching 3
CCD/Astrophotography 16
Astrometric Measurements 14

C. Results by method

1. Standard Project Jupiter Method Results

The accuracy for which the orbital period is determined varies with the observing technique selected. The results for determining the orbital period, independent of the moon selected, is:

Method % Difference
JD Estimating 0.35
Sketching Indeterminate
CCD/Astrophotography 1.2
Astrometric Measurements 0.2

2. With one Assumption Removed

No other JD results were sufficient to meaningfully remove the Section X.A.2 assumption. Therefore, Tim’s results for the mass of Jupiter, at 2.4% accuracy, using this approach is unique.
