This directory contains Ulysses dust data from launch to the end of 1992. These data cover the period 1990-10-28 to 1992-12-29. The data are stored as 1 ASCII table (ULYDDUST.TAB). Each data file has a PDS label file (ULYDDUST.LBL) which describes some of the physical properties of the data. There is a single format file (ULYDDUST.FMT) which describes the columns of the data files. ULYDCODE.TAB, ULYDCALB.TAB, and ULYDAREA.TAB contain information relating to the dust data file. ULYDCODE.TAB contains information regarding codes found in the data, ULYDCALB.TAB contains calibration data, and ULYDAREA.TAB contains information regarding the area of the dust detector exposed to particles as a function of their speed direction. For more information on these files please refer to the corresponding label (.LBL) file. The original instrument description paper [GRUENETAL1992B] has been included here as the file INST.TXT. The file DATASET.TXT provides a textual description of the data including caveats regarding the data usage and reliability. In addition directory /DOCUMENT/DUST/ contains various source documents describing corrections to the published instrument and data descriptions. /-------------------------\ | D A T A | \-------------------------/ These data can be read according to the FORTRAN format statement: '(i5,a25,f13.4,f6.1,5i2,8i3,5i2,f8.5,2f6.1,f8.5,3i4,2f5.1,e9.2,f7.1)' Columns in all data files: ===================================================== name type description ----------------------------------------------------- number i5 number of impact time a25 time in the format yyyy-mm-ddThh:mm:ss.sssZ sector f6.1 angular orientation of sensor axis about spin axis icp i2 ion collector threshold ecp i2 electron collector threshold hv i2 channeltron voltage level ccp i2 channeltron threshold pcp i2 entrance grid threshold ia i3 ion amplitude code ea i3 electron amplitude code ca i3 channeltron amplitude code pa i3 entrance grid amplitude code it i3 ion rise time code et i3 electron rise time code pet i3 entrance grid rise time code eit i3 electron ion time code eic i2 electron ion coincidence iic i2 ion channeltron coincidence evd i2 event definition ar i2 ion amplitude range cln i2 event class sc_r f8.5 spacecraft distance from sun (AU) sc_lon f6.1 spacecraft heliocentric ecliptic longitude (degrees) sc_lat f6.1 spacecraft heliocentric ecliptic latitude (degrees) sc_jup f8.5 spacecraft distance from Jupiter (AU) rot_ang i4 rotation angle s_lon i4 ecliptic longitude of sensor axis (degrees) s_lat i4 ecliptic latitude of sensor axis (degrees) speed f5.1 particle mean impact speed espeed f5.1 factor for upper and lower impactor speed estimate xmass 1pe9.2 mean particle mass exmass f7.1 factor for upper and lower impactor mass estimate Any data column whose value is 9.999, 99.9, 999, 9999.9 or 9.99e+10 (depending upon column format) is a missing data value.
