| 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. | |
| BackgroundQualityParams | DesImageDqc | Quality parameters for the background model image | |
| BackgroundStorage | DesBackgroundMapFitsFile | Storage container for the background model image | |
| CatalogStorage | DesSingleEpochCatalogFitsFile | Storage container for the single epoch catalog data | |
| CCDNumber | int | DECam science CCD number | |
| 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 | DesSingleEpochImageFitsFile | Storage container for the single epoch 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 | |
| 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. This is optional in case of calibration images. | |
| 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 | |
| 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. | |
| Object | str | Object name. Examples: DES survey hex 906-339 tiling 8, Field 74 | |
| Observation | DesObservation | Information about the observation | |
| ProcessingSteps | ListOfProcessingSteps | Information about the processing steps associated with the generation of the image | |
| PsfModelStorage | DesPsfModelStorage | Storage container for the PSF model | |
| QualityParams | DesAstromImageDqc | Quality parameters for the single epoch image | |
| Saturate | float | Global saturation threshold valid for amp A and B | |
| 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,... | |
| WCS | Wcs | The description of the WCS for this image. This is the original WCS solution assigned at acquisition or a WCS soluton derived from this image and intended to be applied at processing time. In either case, the header values of a COPY of the original FITS image are compared to these values and updated as necessary prior to processing. | |
| ZeroPoint | ZeroPoint | The description of the photometric zero point for this image. This is a library zero point, an instrumental zero point, or a zero point solution derived and intended to be applied at processing time. In either case, the header values of a COPY of the original FITS image are compared to these values and updated as necessary prior to processing. | |
