Bus Telemetry CDF File
The Bus Telemetry CDF file is a daily product.
The Common Data Format (CDF) file is written to the International Solar-Terrestrial Physics (ISTP) standard. This CDF file contains many of CASSIOPE’s bus telemetry definitions and their values in binary CDF self describing data.
