Contains JPEG images of fields at various zoom factors, and their astrometry. |
The frame is the basic image unit. The table contains false color JPEG images of the fields, and their most relevant parameters, in particular the coefficients of the astrometric transformation, and position info. The images are stored at several zoom levels. |
