360 frames (0.5° oscillation) at the peak wavelength were collected after the high-remote data. They can be downloaded from [ftp://turn5.biologie.uni-konstanz.de/pub/datasets/3csl-pk.tar here] (1.9 Gb). This peak dataset is somewhat difficult to index; if the results are really bad (e.g. distance refining far away from 370 mm) with the default 180 frames, then just try with 90 or 270 frames.

To investigate further, use
adxv -nopixmap ../../frms/pk/SK3_4_180.img
(you'll have to adjust the path, of course; I use -nopixmap for nxclient access) go to File/Load and then click the "+" button to see the next 50 or so frames - you'll see that there is a "beautiful" system of double reflections.


It is clear that these split reflections provide bad data. Fortunately it seems that in other areas of the detector, the reflections look better.
