Errors are statisical only; The sydtematic error was assigned to be (+/-) 4% for the 140 degree data, (+/-) 6% for the 90 degree data and (+/-) 3% for the 45 degree data. Data at 90 and 140 degrees were taken in Spectrum mode. The data at 45 degrees was taken in Event mode which allowed for off-line replay.

Oxygen internal gas jet target in ADONE storage ring. No magnetic spectrometer; used shower counter with energy resolution of a few %. Because of uncertainty in thickness, data was normalized at 0.540 GeV and 0.730 GeV and 37.1 degrees to the data of O'Connell.
Errors are random. Total systematic error of (+/-) 4.5% dominated by radiative corrections (3%) and calibration of data (3%).

Nuclei: D, C, Fe, and Au
Coulomb corrections have been applied.
Errors are random.
Systematic errors depend somewhat on which spectrometer was used. For the HMS (scattering angles up to and including 55 degrees) the systematic errors are 3.5 - 4%. For the data at larger angles taken with the SOS, the systematic errors are somewhat larger. See http://www.krl.caltech.edu/~johna/thesis/ for complete details.
