PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT INTERCHANGE_FORMAT = ASCII PUBLICATION_DATE = 2007-02-20 NOTE = "MGS E-Kernel Information" END_OBJECT = TEXT END General information about SPICE E-kernels ========================================= The purpose of the Events (E) -kernel is to store different kinds of the spacecraft and science instrument events related information such as spacecraft and instrument commands, status parameters, records of spacecraft activities, ground events, and so on, and to systematize and provide access to this data in relational data base -like fashion. The means of an access to the EK data are provided via collection of FORTRAN 77 subroutines that are part of the SPICELIB library or C functions that are part of the CSPICE library or using SPICE system utility program INSPEKT to browse E-kernel contents. The subroutines/functions can be integrated into user application programs while the INSPEKT program can be used to view E-kernel information interactively. The SPICE system toolkit for a number of computer platforms or information regarding how it can be obtained is located in the "/software" subdirectory of the main directory of this dataset. To use E-kernels with INSPEKT program, a Leapseconds (LSK) is required. Refer to the "ek.req" and "inspekt.ug" documents provided with the toolkit or available from the NAIF Node of PDS if SPICE toolkit is not included with this data set to get more information on how to access E-kernel data.
