Experiment group

Experiment Group

The Experiment_g contains a table (_t) holding all of the high level metadata to describe an experiment. This includes information such as experiment name, description, PI's institutions, network code, and experiment location. Information in this table is later used when extracting metadata in form of stationXML or filling in some of the data header fields (e.g. miniseed data network code field).

• Experiment_g
  • Experiment_t
    • experiment_id_s [string 8] - This is usually an IRIS assigned code in the format ##-####
