Offline Energy Calculation (Apr 1998)
(Temporary link to the
old calculation: Sep-Oct 1997)
Here a graphic comparison between the old and the new calculation:
all the energies ;
psip ;
chi2 ;
1P1 ;
chi1.
The below list is for each stack/resonance in chronological order;
the resonance name is followed by the start date of the data taking and the
"nominal" energy from the logbook.
The avalable links give a table of the calculated energy, the luminosity
(from the web) and the energy weighted with the luminosity
run per run for that particular "nominal" point. It is also available a
plot of the energy, the sigma of the beam and the dL versus time.
The reference orbit used for the calculation is the psi' of stack 67.
The energy calculation keeps in account the saturation of the BPMs.
The BPM calibration has been done from a Dispersion measurement of
the accumulator lattice (May 1997).
NOTE: For those .ps format that are not readable on sgi work stations,
it is available a Low Resolution version.
