The plot shows C^{2}
versus P_{g} for a data set. Listed are the centroid (in green)
and its error (upper right in red) calculated from s/ÖN. We
can also estimate the error in P_{g} from values of P_{g}
when C^{2} = C^{2}_{min}+1. Vary P_{g}
(move the blue square with the mouse) to find values of e
(m - m_{min})
when C^{2} = C^{2}_{min}+1. How
similar is the value you get when compared with the listed 'Error'? Statistical uncertainty decreases indefinitely as 1/ÖN.
However, in
general other factors will also cause the peak position to vary, e.g.
variations in amplifier gain. |
