It appears to take one property line_2: from each class of object. It is either some kind of missing link, or a new line_3: type of activity. Because of the high optical polarization, OI 287 has been line_4: classified with the blazars. However, every other blazar is variable in optical line_5: flux, polarization, and polarization angle., while OI 287 is constant at V=17, line_6: P=8%, and theta=145 degrees. Also, every other blazar has a radio source line_7: dominated by an intense flat-spectrum core, while OI 287 has an upper limit of line_8: 2% of the total 20cm flux in the core. line_10: The only group of quasars which ever shows even moderate (2-5%) constant line_11: optical polarization is the broad absorption line (BAL) objects, e.g. PHL 5200 line_12: and H1413+113. Among the BAL quasars, PHL 5200 and H1413+113 have exceptionally line_13: smooth deep, attached absorption lines, and also the highest polarization. We line_14: want to know whether OI 287 is a BAL quasar. It would be the first definite line_15: radio loud example. If it is a BAL quasar then the high polarization is really line_16: related to (and perhaps the key to) the BAL phenomenon, and we can use the line_17: techniques of spectropolarimetry to help unlock the BAL geometry. The UV line_18: spectral shape would also provide help determining the cause of polarization. ! ! end of abstract general_form_proposers: lname: ULVESTAD fname: J. mi: S. inst: JET PROPULSION LABORATORY country: USA ! lname: ANTONUCCI fname: ROBERT title: PROF. inst: UCSB country: USA ! lname: KINNEY fname: A. mi: L. inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Our observing plan is very simple. We would like 69 min. with the FOS, Red Tube line_2: G190H Grating. Our target, OI 287, has Fnu(1.5mu) = 0.22 m Jy (V = 18) and line_3: Fnu is proportional to nu**(-1.5). Our main goal is to search for broad line_4: absorption blueward of the Si IV lambda 1397 and CIV lambda 1549 emission line_5: lines, which actually appear at 2020 Angstroms and 2240 Angstroms, line_6: respectively. Our other goal is to measure the spectrum slope to help determine line_7: the cause of the high polarization. line_9: The FOS simulator program shows that we can expect SNR 12/diode, which is good line_10: for our purpose. This is our simulation of a featureless power law of line_11: appropriate amplitude and slope: line_13: FIGURE IS SHOWN ! question: 4 section: 1 line_1: The resonance lines normally seen in absorption in BAL quasars appear in the line_2: UV, and this target (V=18, F proportional to nu**(-1.5)) is much too faint line_3: for IUE. Broad absorption rarely appears at MgII lambda 2800, and existing line_4: ground based spectra rule this out for OI 287. ! question: 7 section: 1 line_1: line_2: SDAS and IRAF programs. We have all the necessary programs for measuring the line_3: data, e.g. determining spectral slopes, line flux and equivalent widths, etc. ! question: 9 section: 1 line_1: a. line_2: We've worked for the FOS IDT. ! question: 10 section: 1 line_1: STScI will provide the data analysis packages and computer hardware that we line_2: need. ! !end of general form text general_form_address: lname: ANTONUCCI fname: ROBERT category: PI inst: U.
