Error analysis

  • Generated 1000 stars, fitted them to get the errors.
  • Found the following histograms:
alpha.png rho.png
x_0.png y_0.png
sigma_x.png sigma_y.png
beta_1.png beta_2.png
nu_tot.png  
  • $\chi^2$:
  • chi_2.png
  • So an example:
  Fit
$\alpha$ 0.014399 $\pm$ 0.001715
$\beta_1$ -0.932859 $\pm$ 1.219758
$\beta_2$ -1.4633 $\pm$ 1.321896
$\nu_{tot}$ 1706788.00061 $\pm$ 8431.999936
$\rho$ 0.465381 $\pm$ 0.213149
$\sigma_x$ 4.681192 $\pm$ 1.355603
$\sigma_y$ 5.505599 $\pm$ 1.424252
$x_0$ 29.707376 $\pm$ 1.742497
