Detailed description of the data product¶
Also known as single epoch image in DES terminology. This product is the result of applying the DES single epoch pipeline to a DES Raw Frame Product (science exposure). It contains the single epoch dataset of a single CCD.
The main elements inside this product are:
Instrument: The instrument name (DECam) and telescope name (NOAO).
Filter: The DECam filter name (DECAM_g, DECAM_r, DECAM_i, DECAM_z or DECAM_Y).
WCS: The image astrometric parameters with linear (e.g., CTYPE1, CRVAL2, CRPIX1, CD1_1) and, optionally, non linear terms (PV1_0, PV2_0, …).
ZeroPoint: The photometric reference zero point in magnitude units.
ImgSpatialFootprint (optional): The spatial footprint of the image either in a serie of vertex or a bounding box.
Masks (optional): Euclid bit masks present in the flag image dataset.
Observation: Contains information about the telescope pointing (Telra, Teldec, HourAngle, ZenithDistance, Epoch), the observation night and date, and the optical air mass.
Saturate: Global saturation threshold valid for amplifiers A and B.
Object: The survey object name. For example, DES survey hex 906-339 tiling 8, Field 74.
CCDNumber: The DECam science CCD number (1 to 62).
Scamp: Information about the Scamp processing.
DataStorage: Element that links to a FITS file containing the CCD single epoch image, flag and weight datasets.
PsfModelStorage: Element that links to a FITS file containing the frame PSF model.
BackgroundStorage (optional): Element that links to a FITS file containing the background model.
RunInformation: Information about the processing run (Project and RunNumber).
ProcessingSteps (optional): Information about the processing steps associated with the single epoch process.
