Detailed description of the data product
========================================
.. DetailedDescStart

In its **Data** section, this data product combines a generic SIM input configuration data type, with Simulation and Processing settings specific to the EXT channel. Input star and galaxy catalogues are provided to EuclidExt :term:`PE` by another data product :ref:`SIMTrueUniverseOutput`.

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.

EXT Simulation Settings
+++++++++++++++++++++++

Describes simulation settings specific to SIM_EXT Processing Element. 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
* **ObservationBlockStart**: Date when started the observation block
* **PatternStart**: Date when the dither pattern started
* **ExposureDate**: Date when the dither pattern started
* **FilterName**: The name of the filter to simulate.
* **Psf**:  Point Spread Function (PSF) modeled from stellar sources in the input pixel data [None] 
* **BackgroundMag**: Sky background in AB mag in the specified filter for each detector
* **Zeropoints**: Zeropoints for the different detectors of the simulated image

EXT Processing Settings
+++++++++++++++++++++++

EXT specific processing settings, not included the simulation settings. It contains the following elements

* **Survey**: Survey name to simulate (in KIDS, DES, LSST, CFIS, WISHES, JEDIS, PANSTARRS)
* **ProcessingSteps**: Set of NIP specific processing steps to activate/deactivate
