How do I look up the ZTF code for ER Uma? It will be something like ZTF******* Stewart
VSX lists synonyms, but not for ER UMa it seems. In the case of V1159 Ori it is ZTF22abhvjny
If you need ZTF photometry on ER UMa, you can access it from the the VSX entry on ER UMa, using the “External Links” drop down and selecting “ZTF”.
