you can only check from the logbook. I believe it was 0.05. On the other
hand 0.0 or empty-field are nearly the same.

see above. I understand this sounds "bad" but I have nothing else to
offer. It is not a virtue of elog or paperbook.

If somebody takes data and doesn't write the target thickness in
whichever way, whay am I to say ? My guess is as good as yours.

P.S.
The last alternative is to look at ligit in the file, and/or mfc value
in epics. See scaler/epics ntuple (in scaler.C)
