    public enum NOAOExt

    implements IFitsHeader
    This keyword dictionary defines keywords which may be used in image data recorded by the data acquisition system. It currently does not consider keywords for data processing. Most of the keywords defined here will not be used. New parameters must be added to the logical class heirarchy and then a keyword defined in this dictionary before use in image data.

        public static final NOAOExt CCDSEC
        The unbinned section of the logical CCD pixel raster covered by the amplifier readout in section notation. The section must map directly to the specified data section through the binning and CCD to image coordiante transformation. The image data section (DATASEC) is specified with the starting pixel less than the ending pixel. Thus the order of this section may be flipped depending on the coordinate transformation (which depends on how the CCD coordinate system is defined).

        public static final NOAOExt CCDSIZE

      • CCDSUM

        public static final NOAOExt CCDSUM
        CCD on-chip summing given as two or four integer numbers. These define the summing of CCD pixels in the amplifier readout order. The first two numbers give the number of pixels summed in the serial and parallel directions respectively. If the first pixel read out consists of fewer unbinned pixels along either direction the next two numbers give the number of pixels summed for the first serial and parallel pixels. From this it is implicit how many pixels are summed for the last pixels given the size of the CCD section (CCDSEC). It is highly recommended that controllers read out all pixels with the same summing in which case the size of the CCD section will be the summing factors times the size of the data section.
