Introduction

The NIR Processing Function is in charge of reducing all the NISP imaging data of the Euclid wide survey, analysing the NISP data of the Euclid deep survey, and pre-reducing the NISP spectral data in common with the SIR Processing Function.

The goal of this section is to describe NIR PF Data Products to allow other PFs to designe their interfaces with NIR. A description of the NIR PF can be found on the NIR Software Description Document (SDD, EUCL-OTS-DDD-8-004), which is in turn based on the NIR Requirements Specifications Document (RSD, EUCL-OAR-RS-8-001).

Fig. 12 shows a logical model for the NIR PF workflow.

This is composed by:

• NIR PF Common pre-processing

• NIR PF dither calibration

• NIR PF stacking and catalogue extraction.

However, only a fraction of all Processing Element has been implemented for the SC3. As a result, some of the Data Products do not have detailed descriptions nor corresponding Data Model entries. In the following, we will describe only those Data Products used for the SC3:

• NIR Scientific Data Products

  • NIR Calibrated Frame

  • NIR Stacked Frame

  • NIR Catalogue

• NIR Calibration Data Products

  • NIR Master Dark

  • NIR Master Flat

  • NIR Super-Flat

  • NIR Relative Photometric Calibration factors between detectors

  • NIR Relative Photometric Calibration factors between exposures

  • NIR Relative Photometric Calibration factors between different fields

  • NIR Absolute Photometric Calibration Factors

• NIR PF Settings

  • NIR Configuration Set
