Abstract
The goal of this document is to provide a detailed analysis of the timing inside the DPUs in order to
explain the observed difference in the time-tagging between the detectors in the NISP raw science
files produced during the acquisition of a single exposure and match the need to use a single time
reference for all detectors in the NISP data produced by the SGS Level 1 NISP Processor software.
This document will present a fine correction to the time-tag available in the NISP data products to
determine with a higher accuracy the starting time of the NISP exposure, as well as the starting
time of the data acquisition. These refined times are referred to the on-board time (OBT) already
stored in the digital telemetry of the raw NISP science data.
