Some corrected data

Data correction and reduction code functional

2014-02-24 Brian 0

Before I get started, let me just highlight the new small-angle scattering issue of J. Appl. Cryst. which has come out a few days ago. […]

The error bar: summarising how good your SAXS is.

Speaking of errors: estimating uncertainties in integrated data (corrigendum to “Everything SAXS”)

2014-02-17 Brian 1

I feel I need to make a public apology: it turns out that I have been inaccurate in some of my recent papers on the […]

Internal detection surface diffraction effects leading to a reduction of detected counts (black lines on the real image, over which about 10% fewer counts were detected than the surrounding pixels). Image on the right shows the calculated pattern for the chosen energy. Energy used: 8285 eV, Reflection indices detected: (117). Image courtesy of Christian Gollwitzer at PTB.

Trouble in Paradise? Internal diffraction in PILATUS-like detectors

2014-02-10 Brian 0

A great many of the data correction issues in small-angle scattering can be resolved by trading a kidney for a PILATUS detector [1] (or similar […]

Monte Carlo Demonstration (video)

2014-02-03 Brian 0

Over the last year or so, I have spent quite some words on the Monte Carlo method for extracting (particle) size distributions from scattering data. […]
