Telemetry data schemas

The following sections contain the telemetry message schemas, describing the properties each schema includes, along with their title, unit of measure, and description. Some messages are sent by DISCOS components common to all three telescopes, while others are station-specific. Although certain messages may be delivered on the same topics, their structure might differ depending on the station.
