Model SAXS Test Data for Computation and Demos


This is a model test SAXS dataset to use for both visual and computational tests for the web application "SAXS FrameSlice" hosted at at the SIBYLS beamline at the Advanced Light Source in Berkeley, California USA. The generated data is meant to mimic a SAXS-like dataset that represents a scattering angle (q) vs. intensity (I) step function. For researchers, the dataset makes it easy for investing the properties of SAXS analysis software. For developers, the data aids the ability to write simpler tests for SAXS software application development.

Experimental description:

The data were generated by a shell script. All data start with a q value (abscissa or X-axis) that ranges from 0.004 to 0.04 (inclusive) with a step size of 0.004 in the first column. The intensity values (ordinate or Y-axis ) in the second column begin at a multiple of 100000 for the first 10 data rows, then decreases to a multiple of 10000 for the next 10 data rows. These values are repeated 10 times until reaching a value of a multiple of 0.0001 for the last 10 values at the end of the dataset. The data have a third column that represents an error of 1% of each intensity value.

File description:

There are 8 data files: test_0001.dat through test_0008.dat. The first dataset, test_0001.dat begins with a multiple of 1 for the intensity values, test_0002.dat with a multiple of 2, etc. until the final dataset, test_0008.dat that has a multiple of 8.
