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.
Aucune anomalie est vue au sujet de cette issue. Exemple de traces pour chaque début de salve:

16:12:38.77679, TM_LFR_SCIENCE_BURST_CWF_F2, TIME=0x8000088f7f1b, PA_LFR_ACQUISITION_TIME=0x800008850000
