This page provides a few files to test and manipulate Space-Time-MOC.
Just download and launch the version of Aladin provided below. You can directly load some precomputed STMOCs by clicking & dragging them in Aladin. You can also create your own STMOCs based on catalogs or ephemerids provided below or loaded directly thanks to the Resource tree of Aladin.
If you do not know what is a STMOC, you can load the IVOA STMOC presentation, or/and have a look of the video below.
