For central chips

  • CCD 2:   xoffset = x(slit) - 2030;   yoffset = y(slit) - 4100
  • CCD 3:   xoffset = x(slit) +70;   yoffset = y(slit) - 4100
  • CCD 5:   xoffset = 20 - x(slit);   yoffset = 4150 - y(slit)
  • CCD 8:   xoffset = 2120 - x(slit);   yoffset = 4150 - y(slit)

Outer chips: to avoid for long-slit spectroscopy - only necessary if standard stars need to be observed through a given slit on a MOS mask

  • CCD 1:   xoffset = x(slit) - 3990;   yoffset = y(slit) - 4100
  • CCD 4:   xoffset = x(slit) +2030;   yoffset = y(slit) - 4100
  • CCD 6:   xoffset = -2100 - x(slit);   yoffset = 4150 - y(slit)
  • CCD 7:   xoffset = 4220 - x(slit);   yoffset = 4150 - y(slit)
