SPM-Twin: Wide-Field Sampling & Integration<br />
(complementary limitations)<br />
1.5° Field of View (5400”) = 1.77 square degrees<br />
Lots of sampling elements (“spaxels”): 2.4x10 7 squared arcsecs<br />
a) Full wavelength range with well-chosen spatial<br />
coverage (d-IFUs, fiber-bundles, starbugs)<br />
b) Full spatial coverage with a finite wavelength<br />
range (WFT tunable imager)<br />
