Precise target acquisition is particularly crucial process for a multi-slit spectrographs. This is because of the need to align the mask, within three degrees of freedom, so that each object is positioned at the centre of its intended slit.
There will be several standard procedures to aid in this process. Here will simply outline the specialised commands which may be used:
