Level-2#

VODF Level-2 specifies data products produced by binning the spatial, temporal, and/or spectral components of the Level-1 data over a target-specific or a region of interest of the celestial sphere. These are in instrumental units, e.g. counts.

Tip

This is equivalent to data level 4 (DL4) defined by CTAO, also called “binned-science data”
