----------
channel_id: int
id of channel

the id of the corresponding shower object
ray_tracing_id: int or None
the id of the corresponding ray tracing solution
channel_group_id: int (default: None)
optionally, several channels can belong to a "channel group". Use case is to identify
the channels of a single dual or triple polarized antenna as common in air shower arrays.
