Principal Investigator Institution Country Telephone Dr. Holland C. Ford SPACE TELESCOPE SCIENCE INST USA (301) 338-4803 ------------------------------------------------------------------------------------ 7. Abstract We plan to use the FOS to measure the energy distribution in a knot in the jet from the optical to Ly-alpha in order to measure the spectral index and to look for emission and absorption features. We will take WF/PC pictures in the light of redshifted CIV 1549 and with the red grism to isolate ionized gas near 3C273. We will use the FOS with small apertures to measure the physical characteristics of the ionized gas. We will use the FOS with an occulting aperture to take spectra of the underlying host galaxy. ------------------------------------------------------------------------------------ 8.

Cycle 9: 901-907 ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The SV prerequisite programs for all FOS observations in this program are: Prop ID 2195 FOS Target Acquisition Tests - All observations Prop ID 1317 Int./Ext. Wavelength Offsets - 1st target Prop ID 1318 Spectral Flat Fields - 1st target Prop ID 1320 Absolute Spectrophotometry - 1st visit of bright targets All WF/PC imaging with a center wavelength blueward of 5000 Angstroms requires UV flood ------------------------------------------------------------------------------------ 12. This is an integrated program on 3C273's jet and host galaxy. Data release should not begin until 1 year after 80% of the data has been obtained. ------------------------------------------------------------------------------------ 13. The program is FOS spectrophotometry of 3C273's jet from Ly-alpha through the optical, and spectrophotometry of the host galaxy. We will use WF/PC pictures with the red grism and in the light of redshifted CIV to isolate emission regions for study with FOS. ------------------------------------------------------------------------------------ 11.
