The line_2: first exposure will be a INT ACQ to better center the target line_3: in the COSTAR-corrected FOC FOV, which will not be well line_4: calibrated yet. The rest of the exposures are identical to line_5: those taken in Cycle 1 to demonstrate the improvement COSTAR line_6: makes to the FOC's imaging capabilities. ! question: 7 section: 1 line_1: ! question: 10 section: 1 line_1: Access to several of workstations running IRAF/STSDAS. ! question: 13 section: 1 line_1: ST is uniquely equipped to detect optical emission from synchrotron jets and to line_2: study the interaction of jets with their environment. Here we outline a line_3: program of broad and narrow band imaging and limited slit spectroscopy on line_4: carefully selected sample of objects designed to exploit ST for these purposes. line_5: The aims are to study the following: line_6: - morphological relations between radio and optical emission line_7: - optical and UV counterparts of radio jets and hot spots to derive line_8: information on particle acceleration mechanisms line_9: - interactions between synchrotron jets and the ambient gas, to use each line_10: as a unique probe of the physical conditions within the other line_11: - possible relationship between the propagation of radio jets and star line_12: formation ! !end of general form text general_form_address: lname: SPARKS fname: WILLIAM category: PI inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE country: USA phone: 338-4843 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: 3C449 name_2: 7229+391 descr_1: RADIO JET pos_1: RA = 22H 29M 07.68S +/- 0.1S, pos_2: DEC = +39D 06' 03.9" +/- 1" equinox: 1950 pm_or_par: NO rv_or_z: Z=0.0171 plate_req: N comment_1: PA=10D fluxval_1: V=13.2 ! ! end of fixed targets !
