TimeOffsets 112 1 This table provides derived sampling-rate-adjusted delay time as an offset in milliseconds for computing the time for each data measurement in each RawData Table record. The recorded time stamp provided in the first column of each RawData record is the earth-received time for the sequence of data measurements within that record. To compute the time for a specific data measurement, add the milliseconds time offset, found in this single-record table TimeOffsets for the data measurement column of interest, to the recorded time stamp in the first column of the RawData record containing the data measurement of interest.

RawData 224 71032 This table contains raw SIDE/CCIG scientific measurements extracted from one daily ALSEP ARCSAV tape. Each record contains one SIDE frame which consists of 10 SIDE Data Words WD-1 to WD-10 that provide SIDE/CCIG measurements numbered DI-n, DJ-n, or DF-n. There are 128 SIDE frames, numbered from 0 to 127, in one SIDE cycle before repeating. Each record begins with the earth-received time for the set of data in that record followed by one column for each SIDE Word except for: WD-4 and WD-5 which contain the most and least significant digits, respectively, for one high-energy data reading from the Total Ion Detector that were combined into one data value for this restoration and provided in column WD-4-5; and D-9 and WD-10 which contain the most and least significant digits, respectively, for one low-energy data reading from the Mass Analyzer that were combined into one data value for this restoration and provided in column WD-9-10. SIDE Words WD-2, WD-3, WD-6, WD-7, and WD-8 contain different SIDE measurements depending on the SIDE frame number. For this restoration, the specific SIDE measurement number was identified and provided in the measurement number column that precedes each of the WD-2, WD-3, WD-6, WD-7, and WD-8 data value columns. Records are time-ordered by the earth-received time, in the first column, which is reference for the set of data in that record. The time column and each data measurement column are followed by a quality flag. Carriage-Return Line-Feed 23 0 112 EarthReceivedTime 1 1 ASCII_String 21 %-21s Day of year and time (Universal Time, formatted as yyyy-dddThh:mm:ss.sss) when the first word of the ALSEP frame containing the SIDE WD-1 data measurement within this record was received at a ground tracking and receiving station on earth.
