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 Neptune encounter period by the spacecraft clock from 11009:26:001 through 11978:58:001. 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 C11XXXXX.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 "11" and the last 2 X's are the spacecraft clock mod60 reading. The data are stored as 61 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: C1100926.DAT C1101756.DAT C1103926.DAT C1105342.DAT C1107042.DAT C1108026.DAT C1109712.DAT C1110712.DAT C1113127.DAT C1114111.DAT C1116727.DAT C1117057.DAT C1118842.DAT C1119426.DAT C1121842.DAT C1122356.DAT C1125111.DAT C1126111.DAT C1127827.DAT C1128627.DAT C1131011.DAT C1131427.DAT C1133812.DAT C1138608.DAT C1138856.DAT C1138857.DAT C1139028.DAT C1139153.DAT C1145957.DAT C1146812.DAT C1149026.DAT C1150126.DAT C1154927.DAT C1155757.DAT C1157927.DAT C1158857.DAT C1161027.DAT C1161757.DAT C1163912.DAT C1164857.DAT C1166957.DAT C1167842.DAT C1169657.DAT C1170842.DAT C1172627.DAT C1173912.DAT C1175027.DAT C1175512.DAT C1180012.DAT C1181657.DAT C1183242.DAT C1184527.DAT C1185842.DAT C1187557.DAT C1189227.DAT C1189642.DAT C1192012.DAT C1193557.DAT C1194842.DAT C1196612.DAT C1197857.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 */ /*********************************************************************/
