  • Enum Constant Details

    • APTAREA

      public static final SBFitsExt APTAREA
      Aperture Area of the Telescope used in square millimeters. Note that we are specifying the area as well as the diameter because we want to be able to correct for any central obstruction.

      public static final SBFitsExt APTDIA
      Aperture Diameter of the Telescope used in millimeters.

    • CBLACK

      public static final SBFitsExt CBLACK
      Upon initial display of this image use this ADU level for the Black level.

    • CCD_TEMP

      public static final SBFitsExt CCD_TEMP
      Temperature of CCD when exposure taken.

    • CENTALT

      public static final SBFitsExt CENTALT
      Altitude in degrees of the center of the image in degrees. Format is the same as the OBJCTDEC keyword.

    • CENTAZ

      public static final SBFitsExt CENTAZ
      Azimuth in degrees of the center of the image in degrees. Format is the same as the OBJCTDEC keyword.

    • CWHITE

      public static final SBFitsExt CWHITE
      Upon initial display of this image use this ADU level as the White level. For the SBIG method of displaying images using Background and Range the following conversions would be used: Background = CBLACK Range = CWHITE - CBLACK.

    • DARKTIME

      public static final SBFitsExt DARKTIME
      Total dark time of the observation. This is the total time during which dark current is collected by the detector. If the times in the extension are different the primary HDU gives one of the extension times.

      units = UNITTIME

      default value = EXPTIME

      index = none

    • EGAIN

      public static final SBFitsExt EGAIN
      Electronic gain in e-/ADU.

    • FOCALLEN

      public static final SBFitsExt FOCALLEN
      Focal Length of the Telescope used in millimeters.

    • IMAGETYP

      public static final SBFitsExt IMAGETYP
      This indicates the type of image and should be one of the following: Light Frame Dark Frame Bias Frame Flat Field.

    • OBJCTDEC

      public static final SBFitsExt OBJCTDEC
      This is the Declination of the center of the image in degrees. The format for this is ‘+25 12 34.111’ (SDD MM SS.SSS) using a space as the separator. For the sign, North is + and South is -.

    • OBJCTRA

      public static final SBFitsExt OBJCTRA
      This is the Right Ascension of the center of the image in hours, minutes and secon ds. The format for this is ’12 24 23.123’ (HH MM SS.SSS) using a space as the separator.

    • PEDESTAL

      public static final SBFitsExt PEDESTAL
      Add this ADU count to each pixel value to get to a zero - based ADU. For example in SBIG images we add 100 ADU to each pixel to stop underflow at Zero ADU from noise. We would set PEDESTAL to - 100 in this case.

    • SBSTDVER

      public static final SBFitsExt SBSTDVER
      This string indicates the version of this standard that the image was created to ie ‘SBFITSEXT Version 1.0’.

    • SET_TEMP

    • TRAKTIME

      public static final SBFitsExt TRAKTIME
      If the image was auto-guided this is the exposure time in seconds of the tracker used to acquire this image. If this keyword is not present then the image was unguided or hand guided.
