Dear Professor Fang,

I have a question concerning the feature unitinmm and more especially about its association with the function mcxdettime in Mcxlab.

Shouldn't be detp.ppath multiplied by unitinmm in this function (picture 6&7) ?

In fact, when I try it in a source / detector example in transmission geometry, I have the same results as when I do not use unitinmm concerning the time resolution.

In this example attached, I used unitinmm to transform a 404040 (in mm) grid into a 888 by using a unitinmm factor of 0.2. It is possible to see this difference in the spatial representation (picture 2 &3) but impossible to see it in the time resolution after using mcxdettime (picture 4& blue plot in picture 5).

Therefore, when I implement the unitinmm in a copy of mcxdettime I obtain the coherent result (red plot in picture 5) that I should obtain regarding the theorical result (picture 1).

Thank you in advance for your answer.

Best,
Max
