... GHRS IMAGEs and MAPs are obtained with the focus diodes (see Section on page 80 ) at the ends of the array of main science diodes. ... An IMAGE can only record the light in the 1.74 1.74 arcsec region of the LSA. ... A standard IMAGE will have a pixel spacing of 0.109 arcsec and will cover the entire LSA aperture of 1.74 1.74 arcsec. You may also select pixel spacings of 0.055 or 0.027 arcsec, with proportionately smaller regions of the sky covered in a 16 16 (the default) IMAGE. ...
