Hi Robin

Many thanks for all those suggestions…

Yes, I should give it a try in ISIS too..

I haven’t  investigated thoroughly yet to see if its a consistent thing. I can see temperature changes could be critical, and by ‘orientation’ I presume you refer to flexure effects…

Next time, I’ll gather a few more calibrations throughout the night.
