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 26088:55:001 through 26975:42:001. 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 C26XXXXX.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 "26" and the last 2 X's are the spacecraft clock mod60 reading. The data are stored as 69 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: C2608855.DAT C2608856.DAT C2610525.DAT C2610526.DAT C2612710.DAT C2612711.DAT C2616755.DAT C2616756.DAT C2619755.DAT C2619756.DAT C2622755.DAT C2622756.DAT C2628910.DAT C2628911.DAT C2631940.DAT C2631941.DAT C2634840.DAT C2634841.DAT C2637710.DAT C2637711.DAT C2641640.DAT C2641641.DAT C2646710.DAT C2646711.DAT C2649710.DAT C2649711.DAT C2657225.DAT C2657226.DAT C2658725.DAT C2658726.DAT C2661825.DAT C2661826.DAT C2664710.DAT C2664711.DAT C2665940.DAT C2665941.DAT C2667725.DAT C2667726.DAT C2670810.DAT C2670811.DAT C2671655.DAT C2671656.DAT C2671925.DAT C2671926.DAT C2673855.DAT C2673856.DAT C2674910.DAT C2674911.DAT C2676900.DAT C2677402.DAT C2677634.DAT C2677831.DAT C2679753.DAT C2683611.DAT C2683907.DAT C2684306.DAT C2684653.DAT C2684654.DAT C2684753.DAT C2685304.DAT C2685819.DAT C2685956.DAT C2693105.DAT C2694724.DAT C2694840.DAT C2694955.DAT C2694956.DAT C2697540.DAT C2697541.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 */ /*********************************************************************/
