NAME

spd - SPatial Distortion Program

SYNOPSIS

Synchrotron image corrections and azimuthal integration

DESCRIPTION

SPD stands for SPatial Distortion. Written in C language, this command-line driven program
deals with images coming from X-ray diffusion/diffraction experiments. It does
subsequently:
* intensity corrections (dark current, flat field correction, ...),
* geometry corrections using spline files or a pair of distortion arrays,
* azimuthal integration in 2D or 1D after masking defective pixels. SPD was originally
written by Jorg Klora for ESRF and was re-written by Peter Boesecke from ESRF/ID02.
Maintenance and packaging of the program are provided by Rainer Wilcke and Jerome Kieffer
from SciSoft at ESRF.
