Analysis of VMI Fitting Results for Peaks A, B, D, and G Using Two Fitting Formulas

This report outlines the fitting results from the VMI experiments for various peaks (A, B, D, and G) using two formulas: I=A(1+b2P2(cosq)) and I=A(1+b2P2(cosq)+b4P4(cosq)). The analysis indicates that for each peak, the second fitting formula generally provides improved fits compared to the first one. This trend is consistent across all analyzed peaks, leading to the decision to rely on the second fit in future references due to its better performance in data representation and accuracy.

  1. VMI-fitting results for V(m+i), i=4-10 Helgi Rafn Hróðmarsson – 31/7/14

  2. Two fitting formulas • 1) I=A(1+b2P2(cosq)) • 2) I=A(1+b2P2(cosq)+b4P4(cosq))

  3. V(m+4)

  4. „Peak A“ – fit 1 • I=A(1+b2P2(cosq))

  5. „Peak A“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  6. For Peak A, the second fitting formula gives generally better fits (as to be expected). For future references, we will thusly use the results of the second fit.

  7. „Peak B“ – fit 1 • I=A(1+b2P2(cosq))

  8. „Peak B“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  9. Again, the fits for the second formula give much better results, so they will be used.

  10. „Peak D“ – fit 1 • I=A(1+b2P2(cosq))

  11. „Peak D“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  12. „Peak G“ – fit 1 • I=A(1+b2P2(cosq))

  13. „Peak G“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  14. V(m+5)

  15. „Peak A“ – fit 1 • I=A(1+b2P2(cosq))

  16. „Peak A“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  17. „Peak B“ – fit 1 • I=A(1+b2P2(cosq))

  18. „Peak B“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  19. „Peak D“ – fit 1 • I=A(1+b2P2(cosq))

  20. „Peak D“ – fit 2 • I=A(1+b2P2(cosq)+b4P4(cosq))

  21. „Peak G“ – fit 1 • I=A(1+b2P2(cosq))
