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. | 360 frames (0.5° oscillation) at the peak wavelength were collected after the high-remote data.

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