A secondary g oal of this line_6: project is to search for new Hyades cluster members which mig ht be as faint at line_7: the 25th magnitude, or M(v)=22. This part of the project will be accomplished line_8: through coordinated parallel observations with the WFC to determine proper line_9: motions of very faint stars over a one year base line. line_11: FGS parallax observations of the thirteen Hyades members should yield an error line_12: in the distance modulus of the Hyades Cluster good to approximately 0.014 mag. line_13: This accuracy should be sufficient to eliminate the Hyades as a source of error line_14: in determining the galactic distance scale. ! ! end of abstract general_form_proposers: lname: JEFFERYS fname: WILLIAM mi: H. inst: TEXAS, UNIVERSITY OF country: USA ! lname: BENEDICT fname: GEORGE mi: F. inst: TEXAS, UNIVERSITY OF country: USA ! lname: DUNCOMBE fname: RAYNOR mi: L. inst: TEXAS, UNIVERSITY OF country: USA ! lname: FRANZ fname: OTTO mi: G. inst: LOWELL OBSERVATORY country: USA ! lname: FREDRICK fname: LAURENCE mi: W. inst: VIRGINIA, UNIVERSITY OF country: USA ! lname: HEMENWAY fname: PAUL mi: D. inst: TEXAS, UNIVERSITY OF country: USA ! lname: SHELUS fname: PETER mi: J. inst: TEXAS, UNIVERSITY OF country: USA ! lname: VAN ALTENA fname: WILLIAM mi: F. inst: YALE UNIVERSITY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Cycle 1 5.00 hours line_2: Cycle 2 21.67 hours line_3: Cycle 3 8.67 hours line_4: Cycle 4 13.00 hours line_5: Cycle 5 8.67 hours ! question: 4 section: 1 line_1: Ground-based parallaxes are in the best cases limited to an accuracy of 0.002 line_2: arcsec, which is some 4 times poorer than the projected accuracy from the ST. line_3: Based on this accuracy, we would have to determine parallaxes for about 350 line_4: stars in the Hyades in order to determine the distance modulus to 0.01 mag. line_5: This is not really possible since the total stellar content of the cluster is line_6: also about 350 and many of the stars are too bright to observe accurately. ! question: 5 section: 1 line_1: Parallax observations must be made during the times when the parallax factor is line_2: at a maximum in order to achieve the highest possible accuracy in the parallax. line_3: The time tolerance of +/- 21 days in the observation dates is already at the line_4: maximum level that is acceptable. ! question: 6 section: 1 line_1: All of the FGS observations must be uninterrupted in order to minimize the line_2: effects of thermal drifts in the ST structure. ! ! question: 10 section: 1 line_1: Computational facilities and the ADRS software package. ! question: 12 section: 1 line_1: In order to obtain the highest possible accuracy, it is necessary to operate in line_2: a purely differential manner. In the case of the FGS, this means that the line_3: target field should always be placed in precisely the same part of the FGS line_4: pickle. In this case we are most concerned with local errors in the field line_5: distortion and encoders. These errors can be minimized if we are careful to line_6: keep our measurements as differential as possible. To accomplish this we must line_7: orient the ST at the same roll angle for each observation at epochs 1, 3 and 5 line_8: and 180 degrees from that angle for epochs 2 and 4. Since each observation line_9: will take about 10 minutes, it is possible to complete all of the 4 or 6 line_10: observations for one epoch during one orbit. ! question: 13 section: 1 line_1: Trigonometric parallaxes will be obtained for about 10 Hyades cluster members line_2: to determine the distance modulus of the Hyades cluster to about 0.01 mag. WFC line_3: exposures will be taken of about 20 regions in parallel mode to search for new line_4: faint members of the cluster to about the 25th magnitude using proper motions line_5: as the membership criterion. !
