We advertise a potential list of projects that are candidates for Cycle 10 calibration outsourcing proposals that could be submitted in response to the Cycle 10 call for proposals. This list is not meant to be complete and no guarantee of approval by the TAC is intended or implied. Note that some of these are essentially archival proposals: the data have already been acquired, or they will be acquired in a Cycle 9 calibration program, and one could submit a proposal to analyze these data and create appropriate reference files and documentation.

Ideas Requiring Observing Proposals

Obtain Line Spread Functions for the 52x0.1 and 52x0.2 slits using external objects

Current LSFs for these apertures are based on observations of an extended source through the 52X0.05 slit convolved with model PSFs.

Model CCD ghosts (window reflections) at Y=900

We are implementing new aperture definitions that will permit observations of compact objects (e.g., galactic nuclei) centered at row 900 on the CCD rather than the center. This will ameliorate losses due to decreasing charge transfer efficiency in the CCD. The pattern of reflections at this location will be different. A proposal to observe and analyze this effect would be useful.

Imaging PSF across the field of view, as a function of spectral type

We have observed a grid of stars of different spectral types at the center of the field of view for the purpose of characterizing the STIS PSF. Some data over a narrow range of colors from observations of star clusters exists, but blue spectral types are lacking. See proposals 8422 and 8416.

Ideas using Existing or Planned Calibration Data

Coronographic Wedge PSF Characterization

Data that could be used for this purpose are being obtained in the Cycle 8 calibration proposal 8419, and in the Cycle 9 proposal 8842. Observations of stars spanning a range of colors are being obtained at two wedge locations.

Model CCD window ghosts for G750M spectra

Data that could be used for this purpose are being obtained in the Cycle 9 calibration proposal 8852.

Characterize Spectroscopic PSFs for the 52x0.2, 52x0.2F1 & 52x0.2F2 slits at 10^-6 of peak flux

Data that could be used for this purpose are being obtained in the Cycle 9 calibration proposal 8844.
