| AxisLengths | ListOfInteger4 | List of lengths of each data axis. Analogous to a list of FITS NAXIS1, NAXIS2, ... , NAXISn keywords. | |
| AxisNumber | int | The dimensionality of the data (e.g., number of physical image axes/dimmensions). Analogous to the FITS NAXIS keyword. | |
| BrightStarMasksStorage | MerBrightStarMasksFile | Storage container for the bright star spatial masks | |
| CalblockIdList | ListOfCalblockId | The calibration block ids. | |
| CalblockVariantList | ListOfCalblockVariant | The calibration block variants. | |
| DataLength | int | Total number of individual value elements (pixels, voxels, etc.) in the data set referred to in this instance. Equivalent to AxisLength_0 * AxisLength_1 * ... * AxisLength_AxisNumber. | |
| DataSize | int | Size of an individual data element, in bits, following the FITS convention (i.e., negative for floating point values) such that the total size of the data array is |DataSize| x DataLength bits. | |
| DataStorage | MerMosaicFitsFile | Storage container for the image. | |
| ExposureTime | ExposureTime | Exposure time of the detector elements (i.e., physical pixels) or detector integration time in seconds. This can be a sum or average value of multiple exposures/integrations in some cases, and can be zero for certain calibrations. Analog to FITS EXPTIME keyword. | |
| Filter | BaseFilter | Instrument filter name | |
| FilterTransmissionStorage | MerFilterTransmissionFitsFile | Storage container for the average filter transmission wavelength | |
| FirstObservationDateTime | MerObservationDateTime | Observation date time of the first Euclid observation used to generate the product | |
| FlagStorage | MerMosaicFlagFitsFile | Storage container for the pixel flags | |
| ImgArea | ImgArea | Information about the coverage of the image relative to the full focal plane. This can refer to an individual detector, a sub-region of a detector, or even multiple detectors (e.g., a quadrant or entire focal plane). In other words, it would be any logical data segment that normally would be stored in a data array. | |
| ImgNumber | int | Number of image areas (ImgArea) representing a single observation or exposure. | |
| ImgSpatialFootprint | SpatialFootprint | This spatial area defines the spatial footprint of the image in a serie of vertex. Vertex should be expressed in RA/DEC. This spatial footprint could be processed by LE1 with pointing parameters and updated by VIS/NIR/EXT processing functions that compute the astrometric solution. | |
| ImgStatistics | ImgStats | Information about the statistics of the image pixels [None] | |
| ImgType | DataProduct | Complex description of the image type based on ESO definitions. | |
| Instrument | BaseInstrument | Instrument information | |
| LastObservationDateTime | MerObservationDateTime | Observation date time of the last Euclid observation used to generate the product | |
| LayersStorage | MerLayersFitsFile | Storage container for the data input layers information | |
| Masks | str | Euclid bit masks present in the flag image dataset, optional. Please use this pattern naming : XXXImgBitMaskDef where XXX is your Processing function acronym. | |
| ObservationIdList | ListOfObservationId | List of unique IDs identifying the Euclid observations overlapping with the studied region. | |
| PatchIdList | ListOfPatchId | The sky patch ids. | |
| ProcessingMode | str | MER pipeline processing mode used to generate this product. | |
| ProcessingSteps | ListOfProcessingSteps | Information about the processing steps associated with the generation of the product | |
| PsfModelStorage | MerMosaicPsfFitsFile | Storage container for the PSF model | |
| QualityParams | MerImageDqc | Quality parameters for the mosaic image | |
| ReferenceObservationDateTime | MerObservationDateTime | Reference observation date time for GAIA proper motion correction | |
| RmsStorage | MerMosaicRmsFitsFile | Storage container for the rms/error | |
| SimInputConfId | str | This Id is inherited from the sim request that was used to process this simulated image. 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,... | |
| TileIndex | int | MER tile index. | |
| WCS | Wcs | The description of the WCS for this image. It should mirror the values in the FITS header. This is not the WCS solution that has been applied to the pixels. | |
| ZeroPoint | ZeroPoint | The effective photometric zero point of this stack of singleImages | |
