These observations will permit the instrumental line_5: polarization to be calibrated. The instrumental polarization must be line_6: determined to a high precision in order to vectoriallly remove it from line_7: HSP polarization observations to determine the actual astronomical line_8: polarization. Final run of proposal will look at one of 2 possible line_9: stars previously observed to get another look at the throughput. line_10: Revision History: Mark H. Slovak 8/30/88 line_11: Translated to V2 proposal instructions (RPSS V6.2) S. Laurent 1/20/89 line_12: Updated: Sally Laurent 2/24/89, 3/20/89, 4/13/89, 5/12/89 line_13: Modified: P. Stanley 1/15/90 - change to use CTA selected targets only; line_14: Fixes for aberration problem - SALM 7/30/90; Based on SV/HSP 1386. line_15: New submission changed targets and revised scheduling strategy. line_16: Revised: 26 Aug 92 J. Dolan, L. Walter, P. Reppert line_17: want to re-run the proposal (3985) one last time to bring down errors. ! ! end of abstract general_form_proposers: lname: BLESS fname: R. mi: C. inst: UNIVERSITY OF WISCONSIN country: USA ! lname: SLOVAK fname: M. mi: H. inst: UNIVERSITY OF WISCONSIN country: USA ! lname: DOLAN fname: J. mi: F. inst: GODDARD SPACE FLIGHT CENTER country: USA ! lname: WALTER fname: LISA mi: E. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The proposed observations will use the polarimetric IDT (IDT#1, POL) line_2: configured in the digital, single aperture mode. The observations line_3: complement proposal 3985, with the intention of reducing the error line_4: bars determined from reduction of that data. ! question: 3 section: 2 line_1: ! question: 5 section: 1 line_1: If HD115271 observations are difficult to schedule, choose HD176425. line_2: We MUST have FINE LOCK to reduce the jitter contributing to the line_3: errors in the 3985 data. ! question: 6 section: 1 line_1: ! question: 7 section: 1 line_1: Data reduction consists of determining the count rates through each line_2: filter-polarizer combination at each ST roll angle for each of the line_3: unpolarized stars observed. The data analysis involves using the line_4: Fesenkov-Ohman analytical relations to calculate the percent line_5: polarization and the plane of polarization relative to the line_6: appropriate polarizer orientation from the count rates for each line_7: star. In addition, the count rates from observation of the same line_8: unpolarized star in different polarizer locations on the same filter line_9: will be used to derive the relative scale factors between the line_10: polarizers. These scale factors will be derived for all stars line_11: observed to confirm that they are independent of count rate. line_12: The values of the instrumental polarization parameters and the polarizer line_13: relative scale factors will be supplied to the Calibration Data Base. ! question: 8 section: 1 line_1: No need for supporting or coordinated observations with other line_2: facilities is anticipated nor are any additional special line_3: requirements forseen. ! question: 10 section: 1 line_1: Data reduction and analysis will be supported on two computer line_2: facilities at the University of Wisconsin in Madison: line_4: a) a VAX 11/780 computer under the VMS operating sustem with line_5: extensive application software; line_6: b) a microvax cluster under the Ultrix operating system; line_8: Both computer facilities support the FITS standards and thus can line_9: readily access the ST-FITS data export products. ! !end of general form text general_form_address: lname: DOLAN fname: JOE mi: F. category: CON inst: GSFC addr_1: CODE 681 city: GREENBELT state: MD country: USA phone: 301-286-5920 ! lname: BLESS fname: ROBERT mi: C. category: PI inst: UNIVERSITY OF WISCONSIN addr_1: 475 N.
