Project
Jupiter
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.
