[Go-essp-tech] Out-of-bounds data and QC level 1 checks

[martin.juckes at stfc.ac.uk]

Hello Michael, 

It might be useful to separate the QC L1 discussion, which has to be
finalised, from the QC L2/L3 issues which are more complex and have
METAFOR dependencies. We need to test our QC L1 procedure in the coming
weeks in order to have it operational in time to publish data. 

Has any code been written to evaluate the QC L1 tests listed in your
document? 

Cheers,
Martin
