Eta Car will also be observed in line_6: F658N, F410M, and F1042M in the PC to provide second line_7: epoch information on the nebula for comparison with line_8: data obtained during Cycle 1 and to provide a baseline line_9: for later proper motion studies. Additional observa- line_10: tions in F658N two years later will further enhance line_11: the baseline. ! question: 6 section: 1 line_1: For all observations, the field needs to be oriented line_2: so that the bleed columns from the star do not affect line_3: the jet and disk plane of the system. In the WFC line_4: observations, this is accomplished by choosing which line_5: CCD to place the object in, according to the first line_6: scheduleable orientation. The WFC observations can line_7: be scheduled for ANY orientation by selecting the line_8: appropriate CCD. Because there is only one PC chip, line_9: these observations are more tightly constrained, but line_10: still allow for scheduling with a wide range of line_11: orientations, broken into two ranges 180 degrees line_12: apart. The first of these (-89 +/- 54) is preferable line_13: to the second because it puts the E condensation into line_14: the WFC. However, if the second orientation can be line_15: scheduled well in advance of the first, it should line_16: be. The object is changing with time. The WFC images line_17: are to be directly compared with ERO WFC images in line_18: other filters, and the PC observations are first line_19: epoch observations for later proper motion studies. line_20: As a result, it is desireable to schedule the line_21: observations as soon as is feasible. ! !end of general form text general_form_address: lname: HESTER fname: JEFF mi: J. category: CON inst: ARIZONA STATE UNIVERSITY addr_1: DEPT OF PHYSICS AND ASTRONOMY addr_2: BOX 871504 city: TEMPE state: AZ zip: 85287 country: USA phone: (602) 965-0741 ! lname: WESTPHAL fname: JAMES mi: A. title: PROF. category: PI inst: CALTECH addr_1: M/S 170-25 addr_2: DIVISION OF GEOLOGICAL addr_3: & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: (818) 395-4900 ! ! end of general_form_address records ! fixed_targets: targnum: 1 name_1: ETA-CAR descr_1: A, 146, 151, 926 pos_1: RA= 10H 43M 06.87S +/-0.1", pos_2: DEC= -59D 25' 16" +/-0.1" equinox: 1950 comment_1: ERUPTIVE/VARIABLE STAR ! end of fixed targets exposure_logsheet: linenum: 1.001 targname: ETA-CAR config: WFPC2 opmode: IMAGE aperture: WF3-FIX sp_element: F656N num_exp: 2 time_per_exp: 0.11S priority: 1 param_1: CR-SPLIT=NO, param_3: ATD-GAIN=15 req_1: SAME POS FOR 1.002-1.003 AS 1.001 ; req_2: ORIENT 104D +/- 45D; req_3: CYCLE 4 / 1.001-1.003; req_4: SEQ 1.001-1.003 NO GAP comment_1: SEQUENCE TO OBSERVE ETA-CAR THROUGH comment_2: F656N TO MATCH ERO OBSERVATIONS.
