It is likely line_5: that the UV upturn is due to the presence of very hot luminous line_6: post-AGB stars of some kind. The aim of these observations is to line_7: resolve the source of the UV upturn into stars and to learn more line_8: about the AGB luminosity function in early type galaxies. general_form_proposers: lname: TRAUGER fname: JOHN title: PI mi: T inst: JPL country: USA lname: MOULD fname: JEREMY inst: CALTECH country: USA lname: CLARKE fname: JOHN inst: UNIV.

With WFPC2 we expect a limiting V magnitude in 75 line_5: minutes of V = 27.6 mag. question: 4 section: 1 line_1: WFPC2 offers the highest spatial resolution UV imaging yet proposed. WFPC2 line_2: offers the deepest optical imaging likely to be achieved this decade. line_3: stlook2 says 0.106 electrons/second for a V=25 B0 star through nf160w. general_form_address: lname: Trauger fname: John mi: T category: PI inst: JPL addr_1: 4800 Oak Grove Drive city: Pasadena state: CA zip: 91109 country: USA phone: 818 354 9594 fixed_targets: targnum: 1 name_1: NGC6397 descr_1: C,201 pos_1: RA=17h40m41.5s +/- 2", pos_2: DEC=-53d30'25" +/- 2" equinox: 2000 pm_or_par: N fluxnum_1: 1 targnum: 2 name_1: NGC7099 descr_1: C,201 pos_1: RA=21H40M22.0S +/- 2", pos_2: DEC=-23D10'44" +/- 2" equinox: 2000 pm_or_par: N fluxnum_1: 1 targnum: 3 name_1: NGC1978 descr_1: D,201 pos_1: RA=5H28M41.3S +/- 2", pos_2: DEC=-66D16'24" +/- 2" equinox: 1950 pm_or_par: N fluxnum_1: 1 targnum: 4 name_1: M32 descr_1: E,304 pos_1: RA=0H42M41.7S +/- 2", pos_2: DEC=40D50'29" +/- 2" equinox: 2000 pm_or_par: N comment_1: THIS FIELD IS 85"S OF NUCLEUS comment_2: AS REQUESTED BY WFPC1 TEAM fluxnum_1: 1 targnum: 5 name_1: NGC205 descr_1: E,304 pos_1: RA=0H40M22.0S +/- 2", pos_2: DEC=41D41'7" +/- 2" equinox: 2000 pm_or_par: N fluxnum_1: 1 exposure_logsheet: linenum: 1.000 sequence_1: DEFINE sequence_2: UV targname: # config: WFPC2 opmode: IMAGE aperture: WFALL-FIX sp_element: F160BW num_exp: 2 time_per_exp: 2000S priority: 1 param_1: CR-SPLIT=0.6, param_2: CR-TOLERANCE=0.2, param_3: ATD-GAIN=7 req_1: GROUP 1-2.1 NO GAP; req_2: GROUP 1-2.1 WITHIN 1D; req_3: POS TARG 33,33 / 1-2; linenum: 2.000 sequence_1: DEFINE sequence_2: UV targname: # config: WFPC2 opmode: IMAGE aperture: WFALL-FIX sp_element: F555W num_exp: 1 time_per_exp: 10S priority: 1 param_1: CR-SPLIT=NO param_2: ATD-GAIN=15 req_1: SAME POS FOR 2-2.1 AS 1; req_2: SAME ORIENT FOR 2-2.1 AS 1 linenum: 2.100 sequence_1: DEFINE sequence_2: UV targname: # config: WFPC2 opmode: IMAGE aperture: WFALL-FIX sp_element: F555W num_exp: 1 time_per_exp: 100S priority: 1 param_1: CR-SPLIT=NO param_2: ATD-GAIN=15 linenum: 3.000 sequence_1: DEFINE sequence_2: VIS targname: # config: WFPC2 opmode: IMAGE aperture: WFALL-FIX sp_element: F555W num_exp: 2 time_per_exp: 2000s param_1: CR-SPLIT=0.6, param_2: CR-TOLERANCE=0.2, param_3: ATD-GAIN=7 req_1: GROUP 3-4 NO GAP; req_2: GROUP 3-4 WITHIN 1D; linenum: 4.000 sequence_1: DEFINE sequence_2: VIS targname: # config: WFPC2 opmode: IMAGE aperture: WFALL-FIX sp_element: F814W num_exp: 2 time_per_exp: 2000s fluxnum_1: 1 priority: 1 param_1: CR-SPLIT=0.6, param_2: CR-TOLERANCE=0.2, param_3: ATD-GAIN=15 req_1: SAME POS FOR 4 AS 3; req_2: SAME ORIENT FOR 4 AS 3 linenum: 6.000 sequence_1: USE sequence_2: VIS targname: NGC6397 req_1: CYCLE 4 linenum: 7.000 sequence_1: USE sequence_2: UV targname: NGC7099 req_1: CYCLE 4 linenum: 8.000 sequence_1: USE sequence_2: UV targname: NGC1978 req_1: CYCLE 4 linenum: 9.000 sequence_1: USE sequence_2: UV targname: M32 req_1: CYCLE 4; req_2: ORIENT 180D +/- 10D comment_1: THIS ANGLE SPECIFIED BY WFPC1 TEAM linenum: 10.000 sequence_1: USE sequence_2: UV targname: NGC205 req_1: CYCLE 4 !~~~RPSS~~~,PSTANLEY,5209.prop, 8-MAR-1994 09:06
