PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2002-09-19 NOTE = "INFO.TXT describes the contents of this directory." END_OBJECT END This directory contains the 60 millisecond high rate data from the Radio Astronomy instrument on Voyager 2. There data were collected from the Uranus encounter period by the spacecraft clock from 27006:26:001 through 27721:12:001. Data are provided for calibrated wave flux density measurements at 4 given frequencies, 921600 Hz, 614400 Hz, 614400 Hz, and 307200 Hz, and a bandwidth of 200 Hz. The files in this directory are named by C27XXXXX.DAT. The numerical part of the file name is associated with the spacecraft clock reading for the first record in each file. The first 3 X's are the spacecraft clock mod 16 reading without the leading "27" and the last 2 X's are the spacecraft clock mod60 reading. The data are stored as 41 IEEE binary files (.DAT), each accompanied by a PDS label file (.LBL) which describes the properties of the data files. The data files are listed as below: C2700626.DAT C2700627.DAT C2703525.DAT C2703526.DAT C2709625.DAT C2709626.DAT C2712625.DAT C2712626.DAT C2716410.DAT C2716411.DAT C2718755.DAT C2718756.DAT C2721355.DAT C2721356.DAT C2724525.DAT C2724526.DAT C2727355.DAT C2727356.DAT C2730510.DAT C2730511.DAT C2733355.DAT C2733356.DAT C2736510.DAT C2736511.DAT C2738425.DAT C2738426.DAT C2748455.DAT C2748456.DAT C2751425.DAT C2751426.DAT C2754625.DAT C2754626.DAT C2757425.DAT C2757426.DAT C2759525.DAT C2759526.DAT C2766456.DAT C2769525.DAT C2769526.DAT C2772110.DAT C2772111.DAT ================================= 60MILLISECOND HIGH RATE DATA ================================= /*********************************************************************/ /* HEADER_TABLE */ /* ROW / \ */ /* ------------------- */ /* 1 | 28-byte Eng rec | */ /* ------------------- */ /* Header Table Structure */ /* */ /* short Byte 1 Byte 2 */ /* word -------------------------------------------------- */ /* 1 | year | year | */ /* -------------------------------------------------- */ /* 2 | day of year | doy (jan 1 = 1) | */ /* -------------------------------------------------- */ /* 3 | hour | minute | */ /* -------------------------------------------------- */ /* 4 | second | S/C 1=VG1, 2=VG2 | */ /* -------------------------------------------------- */ /* 5 | Integral FDS | Integral FDS | */ /* -------------------------------------------------- */ /* 6 | Fractional FDS | Freq 1 | */ /* -------------------------------------------------- */ /* 7 | Freq 1 | Freq 1 | */ /* -------------------------------------------------- */ /* 8 | Freq 1 | Freq 2 | */ /* -------------------------------------------------- */ /* 9 | Freq 2 | Freq 2 | */ /* -------------------------------------------------- */ /* 10 | Freq 2 | Freq 3 | */ /* -------------------------------------------------- */ /* 11 | Freq 3 | Freq 3 | */ /* -------------------------------------------------- */ /* 12 | Freq 3 | Freq 4 | */ /* -------------------------------------------------- */ /* 13 | Freq 4 | Freq 4 | */ /* -------------------------------------------------- */ /* 14 | Freq 4 | Bandwidth | */ /* -------------------------------------------------- */ /* F1-F2 TIME SERIES - FREQUENCIES 921600hz and 614400hz */ /* / \ */ /* --------------------------------------------------- */ /* 2 |f1,f2|f1,f2| 400 32-bit high rate sample pairs| 4.44444ms */ /* --------------------------------------------------- gap */ /* | for frequencies 1 and 2 | between */ /* --------------------------------------------------- rows */ /* | | */ /* --------------------------------------------------- 60ms */ /* | |f1,f2| |f1,f2| | ... | between */ /* --------------------------------------------------- rows */ /* | \ / | */ /* | 0.1388888 ms between sample pairs| */ /* --------------------------------------------------- */ /* | | */ /* --------------------------------------------------- */ /* . */ /* . */ /* . */ /* --------------------------------------------------- */ /*401 | | */ /* --------------------------------------------------- */ /* F3-F4 TIME SERIES - FREQUENCIES 614400hz and 307200hz */ /* / \ */ /* --------------------------------------------------- */ /*402 |f3,f4|f3,f4| 400 32-bit high rate sample pairs | 4.44444ms */ /* -------------------------------------------------- gap */ /* | for frequencies 3 and 4 | between */ /* -------------------------------------------------- rows */ /* | | */ /* --------------------------------------------------- 60ms */ /* | |f3,f4| |f3,f4| | ... | between */ /* --------------------------------------------------- rows */ /* | \ / | */ /* | 0.1388888 ms between sample pairs| */ /* --------------------------------------------------- */ /* | | */ /* --------------------------------------------------- */ /* | . | */ /* | . | */ /* | . | */ /* --------------------------------------------------- */ /* 801 | ... |f3,f4|f3,f4| */ /* --------------------------------------------------- */ /* 1600 byte data records */ /*********************************************************************/
