---

The following central wavelength settings are available-but-unsupported.

Table A.3: Unsupported Central Wavelength Settings

Grating	Central Wavelength (Å)	Why Unsupported
G750L	8975	Confused by second order
G750M	10363	Confused by second order

Additionally, two central wavelength settings originally offered in the Cycle 7 Handbook were found not to be achievable with STIS, and these have been removed from the available-but-unsupported complement. They are:
