### B.2.7 SuperCosmos

Specialist display functions for use with the SuperCOSMOS survey. These functions display cutout images from the various archives hosted at the SuperCOSMOS Sky Surveys (http://www-wfau.roe.ac.uk/sss/). In most cases these cover the whole of the southern sky.

`sssShowCutout( ra, dec, pixels )`
  Displays a cutout image in one of the available bands from the SuperCOSMOS Sky Surveys. The displayed image is square, and `pixels` pixels in the X and Y dimensions. Pixels are approximately 0.67 arcsec square. Sky coverage is complete.

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowCutout( ra, dec )`
  Displays a cutout image of default size in one of the available bands from the SuperCOSMOS Sky Surveys. Sky coverage is complete.

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
  - Return value
    - (String): short log message
`sssShowBlue( ra, dec, pixels )`
  Displays a cutout image of default size from one of the blue-band surveys from SuperCOSMOS. Sky coverage is complete.

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowRed( ra, dec, pixels )`
  Displays a cutout image of default size from one of the red-band surveys from SuperCOSMOS. Sky coverage is complete.

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowUkstB( ra, dec, pixels )`
  Displays a cutout image taken from the SuperCOSMOS Sky Surveys UK Schmidt Telescope Bj-band survey. The displayed image is square, and `pixels` pixels in the X and Y dimensions. Pixels are approximately 0.67 arcsec square.

  Sky coverage is -90<Dec<+2.5 (degrees).

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowUkstR( ra, dec, pixels )`
  Displays a cutout image taken from the SuperCOSMOS Sky Surveys UK Schmidt Telescope R-band survey. The displayed image is square, and `pixels` pixels in the X and Y dimensions. Pixels are approximately 0.67 arcsec square.

  Sky coverage is -90<Dec<+2.5 (degrees).

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowUkstI( ra, dec, pixels )`
  Displays a cutout image taken from the SuperCOSMOS Sky Surveys UK Schmidt Telescope I-band survey. The displayed image is square, and `pixels` pixels in the X and Y dimensions. Pixels are approximately 0.67 arcsec square.

  Sky coverage is -90<Dec<+2.5 (degrees).

  - Parameters:
    - `ra` (floating point): right ascension of image centre in degrees
    - `dec` (floating point): declination of image centre in degrees
    - `pixels` (integer): dimension of the displayed image
  - Return value
    - (String): short log message
`sssShowEsoR( ra, dec, pixels )`
  Displays a cutout image taken from the SuperCOSMOS Sky Surveys ESO R-band survey. The displayed image is square, and `pixels` pixels in the X and Y dimensions. Pixels are approximately 0.67 arcsec square.
