Our observations will increase by a factor of ~3 the number of disks observed with COS in this critical age range, and encompass the goals of the Ultraviolet Initiative of Cycle 21. The H2 lines excited by Ly alpha present in the COS spectra of our targets, in combination with our ground-based and Spitzer observations, will allow us to estimate the amount of dust settling of the inner disk, providing us with unprescedented insight into the state of evolution of these mature disks. We will acquire the target either using MIRROR A for the dimmer sources or the FUV G160M 1611 grating for the sources which are too bright to observe with MIRROR A. We will follow the acquisition with a brief image in MIRROR A or MIRROR B depending on the source brightness. We will then use the G160M grating set at a central wavelength of 1611 A for the remaining orbit time. Exposure times for all objects were obtained by using COS and STIS FUV through optical observations of other young stars. We chose targets with similar accretion rates (a proxy for the FUV and NUV luminosity) as the input spectrum for the COS ETC, scaled to the distance of our targets and applied extinction values determined from existing optical spectra. We avoid the brightest FUV line (Lyman alpha) by our choice of grating so our targets are safe for the detector. For all targets we ran the ETC using a flux 2X as strong as expected and with no extinction to ensure that the observations are safe. For one source, CVSO 90, which is expected to be a strong accretor and therefore be bright in the UV we will still use the G160M grating but with two different wavelength settings, 1577 and 1623, which will allow us to fill in the gaps in the spectrum while still achieving good S/N.
