KPL/MK Meta-kernel for HERA Dataset v171 -- CReMA 2.1 20241121_001 ============================================================================ This meta-kernel lists the HERA CReMA 2.1 SPICE kernels that provide information for the CReMA 2.1 scenario. - Launch on October, 7th 2024 - Hera trajectory from launch to end of DCP for Launch Period Open (LPO) The kernels listed in this meta-kernel and the order in which they are listed are picked to provide the best data available and the most complete coverage for the HERA CReMA 2.1 scenario. The scenario is based on the following OEM files provided by Mission Analysis: Hera_2024_LPO.oem PO_Didymos.oem PO_Didymos_Barycenter.oem PO_Dimorphos.oem PO_Hera.oem This meta-kernel was generated with the Auxiliary Data Conversion System version: ADCSng v4.3.7. Usage of the Meta-kernel --------------------------------------------------------------------------- This metakernel is only for science operations analysis at this stage. Note that a default Attitude profile has been implemented for the whole mission by the following C-Kernels: hera_sc_crema_2_1_LPO_241007_270303_f181203_v??.bc Reading the comments of the binary C-Kernels is very helpful to understand the implemented attitude. You can use the following NAIF command line utility to extract that information from the kernels: > commnt -r hera_sc_*.bc This file is used by the SPICE system as follows: programs that make use of this kernel must "load" the kernel normally during program initialization. Loading the kernel associates the data items with their names in a data structure called the "kernel pool". The SPICELIB routine FURNSH loads a kernel into the pool. The kernels listed below can be obtained from the ESA SPICE Web server: https://spiftp.esac.esa.int/data/SPICE/HERA/kernels/ or from the ESA SPICE FTP server: ftp://spiftp.esac.esa.int/data/SPICE/HERA/kernels/ Implementation Notes --------------------------------------------------------------------------- DISCLAIMER: Please note that the current kernels are pre-operational and they are subject to change. It is recommended that users make a local copy of this file and modify the value of the PATH_VALUES keyword to point to the actual location of the HERA SPICE data set's ``data'' directory on their system. Replacing ``/'' with ``\'' and converting line terminators to the format native to the user's system may also be required if this meta-kernel is to be used on a non-UNIX workstation. ------------------- This file was created on November 21, 2024 by Alfredo Escalante Lopez ESA/ESAC.
