8.3.6 Error model for Photometry

Author(s): Laurent Galluccio, Marco Delbó, Alberto Cellino

The uncertainty for the G-band photometric flux of the SSO, referred to as $\Phi_{\rm err}$ , was computed using error propagation for the weighted average photometry measured on the corresponding AF CCDs actually used (see Equation 8.14):

$\displaystyle\Phi_{\rm err}$

$\displaystyle=$

$\displaystyle\left(\sqrt{\sum_{i}w_{f_{i}}}\right)^{-1}.$
