Le champ PA_LFR_ACQUISITION_TIME de TM_LFR_SCIENCE_BURST_CWF_F2 est erroné
0%
Description
Le champ PA_LFR_ACQUISITION_TIME de TM_LFR_SCIENCE_BURST_CWF_F2 est erroné:
-Il ne semble pas lié à TIME; pour chaque salve de 8 TM_LFR_SCIENCE_BURST_CWF_F2, on attend une valeur unique (légèrement) inférieure à celle de TIME.
-La salve de 17:31:50.6 est datée "antérieure" à celle de 17:31:40.1, ce qui n'est pas plausible.
A priori, il ne s'agit que d'un pb à la construction du contenu des TM_LFR_SCIENCE_BURST_CWF_F2.
En revanche, la période des TM_LFR_SCIENCE_BURST_CWF_F2 est fonctionnellement correctement implémentées; les mesures faites par l'horloge du PC (potentiellement dégradées par d'éventuelles variations de charge CPU) sont très satisfaisantes.
Le champ TIME est tout à fait vraisemblable.

Les champs TIME et PA_LFR_ACQUISITION_TIME sont désormais cohérents avec la datation par l'horloge du PC malgré les imprécisions possible de cette référence (on observe un écart de quelques ms.
