Finally, we note that this processing of the databases exposed a few mismatches between the names of the structures given in the three databases, which were all reported. Namely, the RCSR nets ucn, rad, jst, fuv and fvb have as IZA-SC names SBN, ATS, JST, NPT and PTT, which did not appear on the RCSR. Additionally, we noticed that 137 structures from EPINET were missing their RCSR name, while 6 RCSR structures mentioned an incorrect EPINET counterpart. This highlights the need for systematic and automated checks of material and topology databases for consistency.
