Understanding DPS Error Detection: Major Contributors and Behavior Analysis

This presentation explains the major contributors to the END0051 behavior in DPS error detection, highlighting the causes of incrementation and the current behavior. It focuses on identifying the primary factors affecting the HKTM point, including ZPD quality flags and spike occurrences.

  1. END0051 behaviour

  2. DPS error detection Cf. IA-MU-1000-6870-AER v4.1 §1.2.2.2.7 & §1.2.2.7 • IMS errors management • EC32 (END0024 • EC21 (END0023) • DPS_EC21_Sum (END0051) • DPS_ELT21_Status • ELT entries in Report format IMS OD Complementary status DPS I/F Checks Image • DMC errors management : • ELT entries • EC32/EC21 counters IIS I/F Checks MAS I/F Checks Interferograms Spectra Processing Algorithms checks The goal of this presentation is not describe all the causes of the END0051 incrementation ; it’s to explain the major contributors in the current behaviour of this HKTM point

  3. Assumptions • END0051 = Accumulation of END0023 (0  END0051  65 535) • END0023 = DPS medium B & minor “error” – elementary counter (0  END0023  255) • Multi-topics counter (Cf. IA-MU-1000-6870-AER v4.1 §1.2.2.7) • END0051 current contain : • The present END0051 behaviour is NOT an abnormal situation of the DPC processing; it represents a synthesis of the flags raised by the scientific algorithms END0051 ZPD quality flag Spike quality flag Flow-chart of the major contributors to incrementation of the END0051 counter Index > Threshold Unsuccessful Research Index > Threshold Cold scenes Invalid Reduced spectra Cold scenes Invalid Reduced spectra Spikes in Calibration interferogram Spikes in Calibration interferogram
