Snapshots of the user interfaces in the Add data tab. The first stage for adding new data is the submitter identification (upper panel). The ordered four-step submission process comes next (middle panel). The user has to either select among existing entries or insert a new one (this pops-up a window with fields to fill), which does not work for the fourth step that concerns the CR data. The latter must be filled one CR quantity at a time (and must belong to the list of quantities declared at the publication step): the bottom panel shows the state of the panel once this step is reached with the energy axis to select, the data file to upload, and the [Graphical check before submission]. We note that help buttons exist for most of the fields to fill at all steps.
