- Enum Constant Detail
  - 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.
  - APTDIA
```
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
```
public static final SBFitsExt SET_TEMP
```
    This is the setpoint of the cooling in degrees C. If it is not specified the setpoint is assumed to be the
  - SITELAT
```
public static final SBFitsExt SITELAT
```
    Latitude of the imaging location in degrees. Format is the same as the OBJCTDEC key word.
  - SITELONG
```
public static final SBFitsExt SITELONG
```
    Longitude of the imaging location in degrees. Format is the same as the OBJCTDEC keyword.
  - SNAPSHOT
```
public static final SBFitsExt SNAPSHOT

```
public static final SBFitsExt SWCREATE
```
    This indicates the name and version of the Software that initially created this file ie ‘SBIGs CCDOps Version 5.10’.
  - SWMODIFY
```
public static final SBFitsExt SWMODIFY
```
    This indicates the name and version of the Software that modified this file ie ‘SBIGs CCDOps Version 5.10’ and the re can be multiple copies of this keyword. Only add this keyword if you actually modified the image and we suggest placing this above the HISTORY keywords corresponding to the modifications made to the image.
  - 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.
  - XBINNING
```
public static final SBFitsExt XBINNING
```
    Binning factor in width.
  - XORGSUBF
```
public static final SBFitsExt XORGSUBF
