LssMasterDarkImage Overview

Query Form

Attribute nameAttribute typeDocstringUnit
AxisLengthsListOfInteger4List of lengths of each data axis. Analogous to a list of FITS NAXIS1, NAXIS2, ... , NAXISn keywords.
AxisNumberintThe dimensionality of the data (e.g., number of physical image axes/dimmensions). Analogous to the FITS NAXIS keyword.
DataLengthintTotal 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.
DataSizeintSize 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.
DataStorageLssMasterDarkTarFileStorage container for the master dark images
ExposureTimeExposureTimeExposure 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.
ImgAreaImgAreaInformation 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.
ImgNumberintNumber of image areas (ImgArea) representing a single observation or exposure.
ImgSpatialFootprintSpatialFootprintThe spatial footprint of the image is the area expressed in a series of vertices that is more accurate than a bounding box. Each vertex should be in units of RA/DEC as the bounding box. 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 the case of calibration images.
ImgStatisticsImgStatsInformation about the statistics of the image pixels [None]
ImgTypeDataProductComplex description of the image type based on ESO definitions.
RaftstrLSST Raft id. "[0-4],[0-4]"
SensorstrLSST Sensor id. "[0-2],[0-2]"
SimInputConfIdstrThis 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,...
