The following line_3: table lists the anticipated lengths and average offsets: line_5: length mean offset line_6: FUV/96 lambda 1200-lambda 6000 3.9 arcsec 7.6 arcsec line_7: NUV/96 lambda 1850-lambda 6000 9.7 arcsec 2.2 arcsec line_8: FUV/48 lambda 1200-lambda 6000 3.9 arcsec 7.7 arcsec line_9: NUV/48 lambda 1850-lambda 6000 4.9 arcsec 1.3 arcsec line_11: The objective prism modes of the two cameras will be used in rather different line_12: fashion. In f/96 the prisms will primarily be used as low-dispersion line_13: spectrographs. Hence for each of these modes we intend to define a "standard" line_14: wavelength and photometrically calibrated position in the central 512x512 line_15: format using the mean offsets listed above. ! question: 3 section: 2 line_1: line_9: Normally, in direct image mode the telescope will be positioned so as to place line_10: the required target in the nominal center of the FOC aperture. (This normal line_11: center will presumably be close to the actual center of the camera format, line_12: unless there are blemishes, reseau or the like at the actual center; this line_13: nominal center is TBD.) line_15: However, in the case of the objective prisms, they yield a dispersed image line_16: which is displaced (by a few arcsec--depending on the prism) from the direct line_17: image of the object. In order to provide the observer with both wavelength and line_18: photometric data, we require that the dispersed image be placed always at the line_19: same nominal position--irrespective of prism used. This means that prism line_20: pointings will contain small offsets, and it is the aim of the SV tests to line_21: confirm the values for these offsets--as well as to provide the necessary line_22: wavelength and spectrophotometry data for their calibration. line_23: All observations are cycle 0. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 7 name_1: FORNAX name_2: NEB descr_1: PLANETARY NEBULA descr_2: WAVELENGTH STANDARD pos_1: RA=02H 39M 49.26S +/- 0.1S, pos_2: DEC=-35D 32' 50.39" +/- 1", pos_3: PLATE-ID=02IV equinox: 2000 comment_1: ALTERNATE TARGET. ! targnum: 8 name_1: RX-PUP descr_1: SYMBIOTIC descr_2: WAVELENGTH STANDARD pos_1: RA=08H 14M 12.4S +/- 0.1S, pos_2: DEC=-41D 42' 28" +/- 1" equinox: 2000 fluxnum_1: 1 fluxval_1: V=11.5 ! targnum: 9 name_1: V1329-CYG descr_1: SYMBIOTIC descr_2: WAVELENGTH STANDARD pos_1: RA=20H 51M 01.2S +/- 0.1S, pos_2: DEC=35D 34' 54" +/- 1" equinox: 2000 fluxnum_1: 1 fluxval_1: V=14 ! ! end of fixed targets !
