Experiment Group

The Experiment_g contains a table holding all of the high level metadata to describe an experiment. This includes metadata such as experiment name, description, PI's, institutions, network code, and location. A detailed description follows.

• Experiment_g

    • experiment_id_s [string 8] - This is usually an IRIS assigned code in the format YYYY-xx
    • net_code_s [string 8] - This is and FDSN assigned newtwork code
    • nickname_s [string 32] - A short descriptive name of the experiment
    • longname_s [string 256] - Long name of the experiment
    • PIs_s [string 1024] - List of principle investigators for the experiment
    • institutions_s [string 1024] - List of institutions involved in experiment
    • summary_paragraph_s [string 2048] - short paragraph describing the experiment or data
    • time_stamp
      • ascii_s [string 32] - time stamp the table was created in an ascii format
      • epoch_l [int 64] - time stamp in epoch seconds
      • micro_seconds_i [int 32] - microseconds to attach to epoch
      • type_s [string 8] - Epoch, ASCII, or BOTH
