Principal Investigator Institution Country Telephone George Hartig STSCI USA 301-338-4966 ------------------------------------------------------------------------------------ 7. Abstract Offsets between internal and external wavelength scales will be measured in SV for 3 gratings on the blue side and for 6 gratings on the red side. This test will be performed using the 0.3",4.3",0,5", and 0.25" x 2.0" aperture and one external source. Derived offsets can be applied to the polynomial fit of pixel number versus wavelength determined from the lines in the internal Pt/Cr-Ne lamp. Unresolved lines in a planetary nebula and in a dMe star will be used to determine the FOS + ST Line Spread Function. The internal sources make up only 5% of the exposure time and must be acquired at the same time as the external sources, so they cannot be scheduled as parallel observations. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. In this test, we will obtain spectra of external and internal wavelength calibration sources, and compare the resulting channel versus wavelength relationships to search for any offset between the two. Both the external objects, as well as the internal Pt-Ne lamp, will be observed through one aperture. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Pointing Requirements: Pointing stability of 10% of smallest aperture used (0.4") - 0.025" stability is required. In the time between the individual exposure pieces, the FOS filter grating wheel MUST NOT be moved. This includes the homing of the instrument that would occur if a non-FOS observation is inserted in the time between the pieces. This restriction also applies to the internal WAVE observations - the filter grating wheel must not be moved between the external and internal observations. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. We require an internal Pt/Cr-Ne lamp observations immediately following each external observation. This test is stray light sensitive. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Data reduction and analysis will be performed at the STScI. Wavelength offsets found between in internal and external sources will need to be incorporated into the dispersion coefficients used by the PODPS pipeline. ------------------------------------------------------------------------------------ 11.
