The file covers the time period 2007-323 04:34:56.212 to 2007-323 07:34:52.983 (beginning orbit 4984)." DESCRIPTION = " This file contains data from ELSSCIL: Electron Spectrometer (ELS) science data (SCI) from the low range (L) of the ELS power supply with up to 128 steps returned in telemetry. These step values are in the SCAN rows of the data files in the form of deflection potential (volts). To convert each step per sector to center electron energies (eV), use the K_FACTORS in the calibration tables (K-factor * defl. volt = eV). Each SCAN row directly corresponds to the previous 16 SENSOR rows where the SENSOR value (c/acc) in a given column is the data sampled at the SCAN value (deflection voltage) in that same column. The SENSOR rows have one more column than the SCAN rows. The additional column is the data quality indicator (last column) for that sensor data. The data values are formatted for a high level of accuracy and DO NOT reflect the accuracy of the intrumentation. The ELS Instrument is mounted on a scanning platform that was activated for the first time in January 2006. The scanner may have moved from its parked position or be in motion for some of this data. Please refer to the Data Set Catalog, ASPERA3_EDR_ELS_DS.CAT, for detailed information about the data organization, science meaning, data quality determination, data modes, etc." ^SPREADSHEET = "ELSSCIL20073230434C_ACCS01.CSV" OBJECT = SPREADSHEET INTERCHANGE_FORMAT = ASCII ROWS = 94080 FIELDS = 8 ROW_BYTES = 1255 /* longest row, too.*/ FIELD_DELIMITER = "COMMA" OBJECT = FIELD NAME = "START TIME" FIELD_NUMBER = 1 DATA_TYPE = TIME BYTES = 21 DESCRIPTION = " The START TIME field specifies the start time of the data sample(s) being returned in the current row in UTC.
