The ESRF SPD SAXS program package (P. Boesecke et al.) for on-line and off-line reduction of SAXS/WAXS data, originally developed for beamline ID02. A set of command-line C programs normalises, azimuthally regroups and averages 2D detector images to 1D profiles with statistical-error propagation, storing data in the ESRF EDF format; common tasks are also available through a GUI in SAXSutilities.
