| 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. | |
| CatalogDataStorage | ExtSefCatalogFitsFile | Storage container for the single detector source catalog. | |
| 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 | ExtSingleEpochFrameFitsFile | Storage container for the single detector image | |
| Detector | str | Information about the detector chip [None] | |
| 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 | |
| FWHM | float | The FWHM of the seeing in arcsec of the SingleEpochFrame. | |
| Gain | ExtGainSet | Gain : This is the list of gain values and their ranges of validity in the image array. | |
| 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 either as a bounding box or a series of vertices. Both the bounding box and the vertices should be expressed in RA/DEC. | |
| ImgStatistics | ImgStats | Information about the statistics of the image pixels [None] | |
| ImgType | DataProduct | Complex description of the image type based on ESO definitions. | |
| Instrument | GroundInstrument | Instrument information | |
| Masks | str | Euclid bit masks present in the flag image dataset, optional | |
| NativeObsId | str | Native Observation ID from the external survey | |
| ObsCollectionDataStorage | ExtObsCollectionFitsFile | Storage container for the association between IDs of objects in the Gaia Catalog and Euclid Detection Catalog and ID of source extractions in the SourceCatalog for this SingleEpochFrame. | |
| ObservationDateTime | GroundObservationDateTime | Date and time of the acqusition of the data stored in this frame. By convention this is the UTC date at the start of the observation. Analog to FITS DATE-OBS keyword. | |
| ProcessParams | ExtScienceFrameParameters | Processing and verification parameters [None] | |
| PsfModelStorage | ExtPsfModelFitsFile | Storage container for the PSF model | |
| QualityParams | ExtSingleEpochFrameDqp | Processing and verification parameters [None] | |
| 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 after astrometric calibration and intended to be applied at processing time. The header values in the associated FITS image should be identical to the values reported here. | |
| Zeropoint | ZeroPoint | Zeropoint of the image including its error and type. The header value in the associated FITS image should be identical to the value reported here. | |
| ZeropointAdditionalInfo | ExtZeropointAdditionalInfo | ZeropointAdditionalInfo : This contains additional information in case recalibration to Gaia has taken place in EXT-PF1 Stage 1. | |
