Why isn't the area swapped when local_ensemble is disabled?

[Ir1d]

Hi,

Thank you for your nice work! When I was going through the code, I was a bit confused by this line: https://github.com/yinboc/liif/blob/main/models/liif.py#L105 .

From the paper I understand that the weight used is the diagnoal area when local ensemble is enabled, but when local ensemble is disabled, the weight used is the current area. I wonder whether this is bug or feature :)

Thanks.
