CLASS data provide the standard deviations of observations as the uncertainties (data_bnds), but ILAMB will assume the data_bnds as lower and upper limits of the observations, i.e. data_bnds[...,0] is the lower limits and data_bnds[...,1] is the upper limits as seen in the following code.

Shall it be fixed in the ilamb code or in the ilamb-data?
