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.

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 for complete details.
