What does the BSEdips option mean in the BSE input file

Dear all,
Could you tell me what the following option means in the BSE input file?
If I open it, what will the yambo output? I have tried, but do not find the difference.
BSEdips= "none" # [BSS] Can be "trace/none" or "xy/xz/yz" to define off-diagonal rotation plane
Best regards.

Dear Youzhao,

this variable is meant to perform the "trace" of the spectrum over the three cartesian direction (IP only), or to define off-diagonal rotation plane for the KERR spectra.

Best,
Daniele
