Detailed Description of the Data Product

In its Data section, this data product combines a generic SIM input configuration data type, with Space Simulation and Processing settings specific to the VIS channel. Input star and galaxy catalogues are provided to EuclidVis PE by another data product True Universe Output Product.

Input Configuration

The input configuration is generic to all SIM simulation channels. It contains the following elements:

  • MagnitudeLimit: Magnitude cut in the MagnitudeLimitFilter in AB system. It applies both to stars and galaxies (optional)

  • MagnitudeLimitFilter: Filter for the magnitude cut in AB system (default: Euclid-H band) (optional)

  • LogHalphaFluxLimit: log(Halpha flux) cut, with Halpha flux in unit of erg/s/cm2/A (optional)

  • RandomSeed: Random seed used and propagated across all the SIM pipeline (optional)

  • SimInputConfId: This Id is propagated in the rest of the pipeline for specific processing. This Id is present ONLY if the productCategory is set to SIMULATION. This Id could transport a full description of the SIM processing parameters or a shortcut for this configuration : CAMPAIGNTTGRISM, ROTATE90GAL,… (optional)

The name of the release is given by the DataSetRelease element in Header section of the data product.

Note that these elements are currently ignored by ELViS_Simulator, because it uses the True Universe Output Product as an input catalog, which already contains these cuts.

Space Simulation Settings

Describes simulation settings common to EuclidNip, EuclidNis and EuclidVis Processing Elements. It contains the following elements:

  • FPAPointing: FPA pointing in Equatorial Coordinates J2000

  • DataProduct: Data product type and category (e.g. Image or Spectrum, Science or Calibration Dark or Flat, etc.)

  • ObservationDate: Observation date of the exposure

  • ObservationMode: Wide Survey or Deep Survey

  • ObservationSequence: Information on the observation sequence in which the exposure is acquired

  • InstrumentMode: Instrument mode during the exposure acquisition

  • Orbit: Predicted satellite orbit (Position, Velocity, Solar aspect angle) at the observation time (optional)

VIS Processing Settings

The VIS specific processing settings data type contains the following elements:

  • Readout: VIS readout mode during the exposure

  • ShutterUnit: Status of the VIS Readout Shutter Unit (RSU)

  • CalibUnit: VIS calibration units: status, intensity level, switch-on and off time

  • ChargedInduced: Status and description of the VIS charge injection mechanism

  • ProcessingSteps: Set of VIS specific processing steps to activate/deactivate
