IFU: Saturation and Sky Counts
Again, these will be essentially the same as with the long-slit spectroscopy mode, except that
- the background limited exposure times on the long-slit spectroscopy page are for the 4 pixel slit; the slits in the mask used with the IFU are 2 pixels wide (and generally give twice the spectral resolution), and
- there are additional losses associated with the IFU optics discussed earlier
Consequently, at least twice as long will be needed for background-limited performance with the IFU!
