This is a python package for processing x-ray scattering data. It was first developed at the X9 beamline at NSLS. Since then, it has been revised multiple times and is now being used at the LiX beamline at NSLS-II. Compared to the previous versions, the major changes in this version are:
-
Revision of the conversion between detector images and the corresponding intensity maps, with coordinates of qr-qz, q-phi, or just q. The conversions are now realized using histograms.
-
2D plot of the data has been improved, with enhanced features to annotate the scattering intensity.
-
Added examples to illustrate the use of this module in various x-ray scattering measurements.

2017: bug fixes related to corrections applied to solution scattering data
2018-01: minor changes in Data2d.conv_Iqphi()
2018-02: changes in Data2d and Data1d to prepare for hdf5 support
2018-07: fixed a bug that caused uneven bins in Data2d.conv_Iq(); first version of hdf5 support
2018-09:
improved functionality and bug fixes for hdf support;
bug fix for slnXS;
fix azimuthal angular range to avoid large gap between values near Pi/-Pi;
attach exp_para to hdf;
removing qgrid from DetectorConfig (this affects the syntax of process/average/merge in slnxs);
