Detailed Description of the Data Product
----------------------------------------
.. DetailedDescStart

This data type contains inputs to simulate a EXT pointing: targeted survey, flux and magnitude cuts, simulation and processing settings, such as pointing information, and instrumental feature switches. It is use as an input for the EXT simulation channel.

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
