[mcstas-users] logarithmic binning detector

[Robert Dalgliesh - STFC UKRI]

Hi,
If I want to create a new detector with logarithmic binning is there an easy way to export the x array?
The way DETECTOR_OUT_1D works requires the binning scheme to be linear.

I would like to define e.g. q bins
1e-3 to 1.0 with 8% binning so the bins are

[a,ab,ab^2,….] where a=1e-3 and b=1.08.

Working out which bin to put data into is straightforward in the same way as linear bins but data output isn’t, due to the constraints of the function above.
In addition, the read function for mcstas plotting would need modification so I guess it will mean an additional function is required unless I’ve missed something.

Obviously, I can write something that outputs the data and post process the x array but that’s not ideal.

Rob
