It is a good idea, thanks. First we need to try to measure the impact of the correction on the data, because our delay correction is already pretty accurate. We could check differences in two cases: when we have delay (K) correction for all spw combined and for each spw individually.
And a second, there's a TEC correction that we may want to use for L-band observations that the VLBI obs. normally do. This was originally only in aips (VLBATECR) but I think it's now working in CASA. Official docs says it only corrects for Faraday rotation but EVN have it now in their reduction guide so may also correct for dispersive delays. The code to do this is as follows:
