Stars like Eps Eri and line_5: Barnard's are prime candidates for this search, because they are close to the line_6: Sun and their motion seems to be perturbed by unseen low-mass companions. The line_7: FOC is very suited to carry out the search, thanks to the photon counting line_8: capabilities, to the high attenuation of the coronograph, and to the small line_9: pixel size resolving the structure of the PSF of the bright primary star. A line_10: roll-blinking technique will be used to improve the detection capabilities. ! ! end of abstract general_form_proposers: lname: LABEYRIE fname: A. inst: CERGA country: FRANCE esa: X ! lname: BARBIERI fname: CESARE inst: PADOVA, UNIVERSITY OF country: ITALY esa: X ! lname: NOTA fname: A. inst: ESA, EUROPEAN SPACE OPERATIONS CENTRE country: ITALY esa: X ! lname: ZINNECKER fname: H. inst: ROYAL OBSERVATORY, EDINBURGH country: UNITED KINGDOM esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: This program is a very difficult one; being largely of exploratory nature it line_2: requires a flexible schedule, with real time decisions. Because the objects we line_3: are looking for are extremely faint, the finalisation of the observing strategy line_4: depends on the actual performance of ST+FOC+HRA, namely on the results of line_5: the SV phase. These considerations mean that the targets, exposure times and line_6: priorities in the Exposure Logsheets are our present best guesses. The target line_7: list comprises a few more objects than observable in the allocated time of 24h, line_8: in order to incorporate in the final scheme information that might come in the line_9: near future from ground observations. The total exposure time in the logsheet line_10: (26.8h instead of 24h) is determined by the inclusion of Prior.3 targets that line_11: may substitute for others not feasible in the GTO. line_12: The observing procedure ROLL is described in detail in Sect.2. ! question: 4 section: 1 line_1: line_3: ST is necessary to: line_4: -provide the highest contrast star/companion, line_5: -reach the 27th-28th V-mag line_6: Diffraction-limited performances, absence of atmospheric turbulence and line_7: diffuse luminosity, extremely accurate tracking all are requisite for a line_8: successfull outcome of this program. ! question: 5 section: 1 line_1: The program is largely of exploratory nature; it also requires a very precise line_2: centering of the bright star under the coronographic finger. Real-time line_3: examination and decisions during at least the first exposures (for each target) line_4: are therefore required. Dark time is absolutely necessary. Flexible schedule line_5: is desirable to accomodate unforeseen discoveries (such as a companion much line_6: brighter than expected). ! question: 6 section: 1 line_1: Dark time absolutely necessary in order to reach the faintest magnitudes and to line_2: be able to properly cancel the wings of the bright star luminosity profile ! question: 7 section: 1 line_1: Real-time analysis is particularly important to: properly center the star under line_2: the finger; decide on any correction; quickly rotate and add and subtract line_3: sub-exposures; evaluate the statistical significance of any clump of photons line_4: indicating the presence of a faint companion; decide on the continuation or not line_5: of an exposure; etc. Off-line analysis includes refined algorithms for best line_6: geometrical and photometric operations; evaluation of celestial coordinates; line_7: etc. This complex of operations should be carried out as quickly as possible line_8: not only for a particular target, but also to optimize the following line_9: observations. line_10: Therefore it is likely that a lengthy stay at the StSci and an heavy use of its line_11: image-processing facilities are required. ! question: 8 section: 1 line_1: The program aims at the direct detection of sub-stellar companions of nearby line_2: stars like EPS-ERI and Barnard's, by making use of the diffraction figure of ST line_3: and of the high resolution, sensitivity and attenuation capability of the line_4: FOC/288 HRA mode. line_5: A ST roll-blinking technique can be used to improve the detection line_6: capabilities. ! question: 10 section: 1 line_1: VAXES and MIDAS, + STARLINK + ASTRONET, HP1000+ IHAP available to PI and line_2: coworkers ! question: 13 section: 1 line_1: We propose to search for planets around nearby stars with the FOC in its line_2: coronographic configuration. A roll-blinking technique will be used to improve line_3: the detection capabilities. ! !end of general form text general_form_address: lname: BARBIERI fname: CESARE category: PI inst: PADOVA, UNIVERSITY OF ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD9826 name_2: UPSILON-AND descr_1: NEARBY BRIGHT STAR V=4.2, GO V pos_1: RA = 1H 36M 47.848S +/- 0.022S, pos_2: DEC = +41D 24' 21.22" +/- 0.33" equinox: 2000 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.011473 ra_pm_unct: 0.000200 dec_pm_val: -0.3565 dec_pm_unct: 0.0030 an_prlx_val: 0.0620 an_prlx_unct: 0.0050 rv_or_z: V=-28 comment_1: FLUX REFERS TO PLANETARY COMPANION fluxnum_1: 1 fluxval_1: V=24+/-1 ! targnum: 2 name_1: HD10700 name_2: TAU-CET descr_1: NEARBY BRIGHT STAR V=3.5, KO V pos_1: RA = 1H 41M 44.660S +/- 0.05S, pos_2: DEC = -16D 12' 00.5" +/- 0.5" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.114667 ra_pm_unct: 0.000200 dec_pm_val: 0.8580 dec_pm_unct: 0.0030 an_prlx_val: 0.2770 an_prlx_unct: 0.0050 rv_or_z: V=-16 fluxnum_1: 1 fluxval_1: V=23+/-1 ! targnum: 3 name_1: HD19373 name_2: IOTA-PER descr_1: NEARBY BRIGHT STAR V=4.2, GO V pos_1: RA = 3H 05M 26.709S +/- 0.05S, pos_2: DEC = +49D 25' 26.63" +/- 0.5" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.084267 ra_pm_unct: 0.000020 dec_pm_val: -0.0780 dec_pm_unct: 0.0030 an_prlx_val: 0.0860 an_prlx_unct: 0.0050 rv_or_z: V=+50 fluxnum_1: 1 fluxval_1: V=24+/-1 ! targnum: 4 name_1: HD22049 name_2: EPS-ERI descr_1: NEARBY BRIGHT ASTROMETRIC BINARY,V=3.7, K2 descr_2: VE pos_1: RA = 3H 30M 34.355S +/- 0.05S, pos_2: DEC = -9D 37' 34.76" +/- 0.5" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.065267 ra_pm_unct: 0.000200 dec_pm_val: 0.0190 dec_pm_unct: 0.0030 an_prlx_val: 0.3020 an_prlx_unct: 0.0050 rv_or_z: V=+16 fluxnum_1: 1 fluxval_1: V=23+/-1 ! targnum: 5 name_1: HD23817 name_2: BETA-RET descr_1: NEARBY BRIGHT ASTROMETRIC BINARY,V=3.8, KO pos_1: RA = 3H 44M 12.055S +/- 0.022S, pos_2: DEC = -64D 48' 25.38" +/- 0.33" equinox: 2000 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.021073 ra_pm_unct: 0.000200 dec_pm_val: 0.0727 dec_pm_unct: 0.0030 an_prlx_val: 0.0490 an_prlx_unct: 0.0050 rv_or_z: V=+51 fluxnum_1: 1 fluxval_1: V=23+/-1 ! targnum: 6 name_1: HD95735 name_2: LALANDE21185 descr_1: NEARBY STAR, ASTROMETRIC BINARY.V=7.5,M2-V pos_1: RA = 11H 00M 36.598S +/- 0.05S, pos_2: DEC = +36D 18' 20.29" +/- 0.5" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.037733 ra_pm_unct: 0.000200 dec_pm_val: -4.7430 dec_pm_unct: 0.0030 an_prlx_val: 0.3970 an_prlx_unct: 0.0050 rv_or_z: V=-84 comment_1: HIGH PM fluxnum_1: 1 fluxval_1: V=27+/-1 ! targnum: 7 name_1: V645-CEN name_2: PROXIMA-CEN descr_1: NEAREST STAR,V=10,M5-E pos_1: RA = 14H 26M 19S +/- 0.05S, pos_2: DEC = -62D 28' 06" +/- 0.5" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.251333 ra_pm_unct: 0.000667 dec_pm_val: 0.7900 dec_pm_unct: 0.0100 an_prlx_val: 0.7610 an_prlx_unct: 0.0050 rv_or_z: V=-16 fluxnum_1: 1 fluxval_1: V=30+/-1 ! targnum: 8 name_1: BD+68D946 descr_1: NEARBY ASTROM.
