✓ For reduction GRACES Fibercould potentially use the<br />

(polarimetry)<br />
Guider<br />
<strong>Gemini</strong> Telescope<br />
✓ For control GRACES will use a cus<strong>to</strong>mized version of<br />
the same software that controls <strong>ESPaDOnS</strong>, with an<br />
interface integrated in<strong>to</strong> existing <strong>CFHT</strong> and <strong>Gemini</strong><br />
software.<br />
