-As for the radiotelescope arrays, different modes of observation of the sky are possible for \gls{HEA} instrumemts, leading to different instrument responses and special analysis schemes. The proposal of ObsCore Extension For Radio Data\footnote{The current note can be found \href{https://www.ivoa.net/documents/ObsCoreExtensionForRadioData/20240614/index.html}{here}.} proposes to add the field {\bf scan\_mode} to qualify this observation property. The values are up to the data providers but pre-defined names are proposed: {\em on-source}, {\em on-off}, {\em raster-map} (that is the grid obervation for \glspl{IACT}), {\em on-the-fly-cross-map} or OTF (when telescopes are slewing between two points of the sky), {\em on-the-fly-map} (that is the wobble observation for \glspl{IACT}).
