Three (3) line_3: unpolarized standard stars wil be observed using various filter-polarizer line_4: combinations for three (3) different roll angles (0d, +60d, +120d). line_5: Two sets of observations will be taken at +30d and -30d to be followed line_6: 60 days later by two more sets of observations at +30d and -30d (for a line_7: total range of 120d). These observations will permit the instrumental line_8: polarization to be calibrated. The instrumental polarization must be line_9: determined to a high precision in order to vectoriallly remove it from line_10: HSP polarization observations to determine the actual astronomical line_11: polarization. line_12: Revision History: Mark H.

The observations divide line_3: into three (3) sequences: line_4: I. Acquire the unpolarized star in the 6.1 arcsec finding aperture of IDT#1 line_5: (POL) with ST at the +30d roll angle. Offset the star to a selected line_6: filter-polarizer pair (F327M, E=0d) and integrate for one (1) minute. line_7: Repeat the observation for the three other filter-polarizer positions in the line_8: order (E=45d, 90d, 135d). Repeat for the other filter-polarizer combinations line_9: (F277M, F237M, F216M, E=0d, 45d, 90d, 135d). Repeat both observations for line_10: one other ST roll angle (-30d from normal). Repeat the entire procedure for line_11: an additional star. line_12: II. 60 days later, with the ST at +30d from normal, acquire and observe line_13: the two (2) stars observed in (I) for all four filter-polarizer line_14: combinations in the order (F327M, F277M, F237M, F216M, E=0, 45, 90, 135d) line_15: integrating for one (1) minute at each position. Repeat the observations line_16: with the ST at a -30d roll from normal. line_17: III. 14 days later than sequence II, with the ST at a roll of 0 degrees line_18: (i.e. at nominal position), acquire and observe one of the stars line_19: previously observed and found to be unpolarized. Observe the star line_20: in all four filter-polarizer combinations in the order: line_21: F327M, F277M, F237M, F216M, E=0, 45, 90, 135d integrating for one (1) line_22: minute at each position. Repeat the observation for a star not line_23: previously observed in order to verify the procedure. ! question: 3 section: 2 line_1: ! question: 5 section: 1 line_1: Close adherence to the sixty (60) day break between parts I and II of line_2: this test is necessary to assure the overall spread in roll angles. line_4: Prerequisites: Schedule this proposal seven or more days after successful line_5: completion of proposal 1381, HSP Mode II Target Acquisition test HSP-02. line_6: Pointing Stability: Coarse track is understood to have less than 19 line_7: marcsec stability. That is satisfactory for all observations in the line_8: 10" and 1.0" UV1, UV2, and VIS apertures, the PMT and the 6.0" (finding) line_9: aperture of POL. HSP requires fine lock for all observations in the line_10: 0.4" apertures and POL's 0.65" apertures. ! question: 6 section: 1 line_1: The ST must be positioned at two special roll angles (-30d and +30d) from the line_2: normal position in order to perform the instrumental calibration procedures line_3: for this test. (See item 3) ! 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 unpolarized line_3: stars observed line_5: The data analysis involves using the Fesenkov-Ohman analytical relations to line_6: calculate the percent polarization and the plane of polarization relative to line_7: the appropriate polarizer orientation from the count rates for each star. In line_8: addition, the count rates from observation of the same unpolarized star in line_9: different polarizer locations on the same filter will be used to derive the line_10: relative scale factors between the polarizers. These scale factors will be line_11: derived for all stars observed to confirm that they are independent of count line_12: rate. line_14: The values of the instrumental polarization parameters and the polarizer line_15: relative scale factors will be supplied to the Calibration Data Base (CDB). ! question: 8 section: 1 line_1: No need for supporting or coordinated observations with other facilities is line_2: anticipated nor are any additional special requirements forseen. ! question: 10 section: 1 line_1: Data reduction and analysis will be supported on two computer facilities at the line_2: University of Wisconsin in Madison: line_4: a) a VAX 11/780 computer under the VMS operating sustem with extensive line_5: 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 readily line_9: 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.
