Dear Jens (and others),
Contrary to what Brian Toby says, uneven step sizes
might be handled by GSAS depending on what the
"unevenness" is. If it is "jitter" about some nominal
step size then use the "RALF" style data format (see p.
174-175 of manual) where the actual step is indicated
for each point and the nominal step size is given on the
"BANK" card. You will also need to give intensity & esd
for each point.
