BepiColombo processing user manual
==================================
== Introduction
We can download TM data from 2 different ways:
* in real-time, or later, we can access from data downloaded during a given day
* some days later, we can access to reconstitued TM database for a given generation date
== SIRIUS data
=== SSH tunnel to JAXA's computer
----
$ SSH_TUNNEL
----
See link:software/bin/SSH_TUNNEL[]
Create an ssh tunnel on port 30200 between localhost and Jaxa reformatter computer (SIRIUS_IP)
This port 32000 is used by Jaxa libsdtp library to download TM data from SIRIUS database
=== Downloading TM
----
$ DOWNLOAD_SIRIUS MEA1/MEA2 yyyy-mm-dd
----
See link:software/bin/DOWNLOAD_SIRIUS[]
Download TM data from SIRIUS database
This script uses dedicated configuration parameters:
* MODE = 2 (SDT_TLMRATE)
* TIME_KIND = 2 (generation time)
* VCID = 48 (merged)
* ANTENNA = 240
It uses also a dedicated SOCKFILE, modified to point to localhost 127.0.0.1:30200
Finally uses another script link:software/bin/DOWNLOAD_EXP[DOWNLOAD_EXP] to download in parallel HK, system HK and science data
== Normal TM data
=== Download data from a given antenna
----
$ DOWNLOAD MEA1/MEA2 yyyy-mm-dd
----
View link:software/bin/DOWNLOAD[]
This script uses dedicated configuration parameters:
* MODE = 2
* TIME_KIND = 1 (reception time)
* VCID = 3 (not standard SDTP => REAL + REPRO)
* ANTENNA = 167 (generic one ?)
== Downloadind data (both case)
----
$ DOWNLOAD_EXP MEA1/MEA2 yyyy-mm-dd
----
View link:software/bin/DOWNLOAD_EXP[]
That script will download in parallel 3 sources of data:
* System-HK (APID 0x0608)
* MEA memory dump (APID 0718)
* MEA1/2 HK (APID 0x628 or 0x630)
* MEA1/2 science (APID 0x528 or 0x530)
Then it will merde the various TM sources in signle L0 binary file
