The following operations are supported. For a formal definition, please review the Service Description.

• GetJpeg
  Returns the bytes of the Jpeg image for a given pointing
  Input 1: RA in degrees (double)
  Input 2: Dec in degrees (double)
  Input 3: Scale, in arcsec/pixel (double)
  Input 4: Width in pixels (int)
  Input 5: Height in pixels (int)
  Input 6: Drawing options (string)
  Output: Image (byte[])
• GetJpegQuery
  Returns the bytes of the Jpeg image for a given pointing.
  Input 1: RA in degrees (double)
  Input 2: Dec in degrees (double)
  Input 3: Scale, in arcsec/pixel (double)
  Input 4: Width in pixels (int)
  Input 5: Height in pixels (int)
  Input 6: Drawing options (string)
  Input 7: Marking selection (string)
  The marking selection string can be:
  • List of objects. RA and DEC columns must be included. Example:
    
    

    ObjId	RA	DEC	RMag
    587731511532060697	18.87684	-0.860973	13.193
    587731511532060708	18.879646	-0.858836	21.078

  • SELECT SQL query. RA and DEC columns must be included. Example:
    
    'SELECT top 10 p.objID, p.ra, p.dec, p.r
    FROM fGetObjFromRect(18.865,18.890,-0.875,-0.845) n JOIN PhotoPrimary p
    ON n.objID = p.objID'
  • String following the pattern: ObjType Band (low_mag, high_mag)
    • ObjType: S | G | P
      S for Stars
      G for Galaxies
      P for both Stars and Galaxies
    • Band: U | G | R | I | Z | A
      to select objects with Band BETWEEN low_mag AND high_mag

      
      Band 'A' will look for all the objects with values betwen low_mag and high_mag for any band (compositions of ORs).
      Only Stars, Galaxies, or PhotoPrimary objects will be marked when magnitude ranges are not specified. Examples:
      
      S
      S R (0.0, 23.5)
      G A (10, 25)

  Output: Image (byte[])
• Revisions
  Return CVS revision numbers
