→How it works
Use imageJ’s circle tool (shift + oval tool) to measure the spot/ring patterns concentric to the (000) direct beam. From the area measurement, the radius (G) is found. From G = 1/d in reciprocal space, the d-spacing is calculated for each measurement made. This plugin has three different modes in which it can operate.
The first, and most basic mode, is '''calculate''' where the calculated values for G and d are added to the imageJ Results window in new columns. G is in nanometers and d is in Angstroms. There is also a 2% error column, which is just 2 % of d in angstroms.
The final mode is '''Overlay & Crop''', which is more of a publication-ready mode that actually crops the diffraction pattern down to the size of the measured region. This is more suitable for publication, as it zooms to the measured region and makes the image square. This image is best saved as a jpeg first and then saved as a tiff if that is the preferred format.
