  "x_description": "EDI Quality Statistics (QSTAT) from Cluster-2 The QSTAT files characterize the beam tracking performance of EDI. They are used by the main processing software to decide whether a data interval is worth to be processed. The QSTAT files contain statistical information about the number of recorded electron beam data in EDI science telemetry. The percentage of spins characterized by at least 4 beams of quality 2 or higher are computed for each 10-minute interval.  The files are stored in a non-standard ASCII format. Each QSTAT file has an introductory comment line that starts with a semicolon (;). The comment line contains the parameters that have been used when running the 'qstat' program. There are two parameters: - min_q : the minimum quality required for recorded beams in telemetry. There are four quality values : 0 = no beam 1 = return beam detected, no time-of-flight information available 2 = return beam detected, time-of-flight information is available, signal-to-noise ratio is below upper threshold level 3 = like 2, but signal-to-noise ratio is above upper threshold level - minbeams : the minimum number of recorded beams of quality >= min_q per spacecraft spin. Any spin with a lower number of recorded beams will be considered as unsuitable for processing by EDI_PISO. Below the introductory comment line are 24 lines, one for each hour of the day. Each line contains eleven columns which are separated by one or more whitespaces. The contents of the columns is: col 0 : date in format yyyy-mm-dd (identical for all 24 lines) col 1 : hour of day (an integer ranging between 0 and 23) col 2 : a flag (an integer that is either 0 or 1). This flag signals if EDI has been in the electron-drift mode (called Windshield Wiper mode) at all during the current hour. col 3 : the total number of spacecraft spins within the current hour (an integer) col 4 : the number of spacecraft spins within the current hour for which the number of recorded beams of quality >= min_q is larger than or equal to minbeams. col 5-10 : for six adjacent 10-minute intervals within the current hour, the percentage of spins with number of recorded beams of quality >= min_q is larger than or equal to minbeams.",
