We expect line_3: virial mass for each cluster and a kinematic distance (statis line_4: where radial velocity observations exist. The radial and azim line_5: of the velocity distribution will be analyzed to determine th line_6: anisotropy in the velocities as a function of distance from t line_7: for three of the clusters. In addition, the degree to which e line_8: energy exists among the various mass groupings will be studie line_9: giants down to one-half solar mass in three of the clusters. line_11: The observations are designed to yield an accuracy of +/- 1 k line_12: derived cluster velocity dispersion at each location in the c line_13: nearer clusters and +/- 2 km/sec for the more distant cluster ! ! 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: The observations for each cluster are divided into four separ line_2: with different exposure levels. Spatially, the regions select line_3: central core, a region east of the center at 10 core radii, a line_4: east and west of the center at 20 core radii. Observations at line_5: radii will be used to study the run of isotropy in the veloci line_6: low density of stars far from the center, it is necessary to line_7: at 20 core radii. Each "exposure" consists of 5 separate expo line_8: each other by small amounts on the order of an arcsec. The pu line_9: offsets is to average out the pixel to pixel variations in th line_10: In addition, the first three of these exposures are taken wit line_11: the last two with the R filter. This group of exposures is de line_12: PC5. Due to image crowding in the center, only a short 25 sec line_13: taken, while at the other positions both a short 100 second a line_14: second exposure is taken. This range of exposures allows us t line_15: horizontal branch to the main sequence with a positional accu line_16: arcsec. These exposures will be repeated after five years to line_17: motions. line_18: The sequence PC10 is used to spatially calibrate the detector line_19: before and after the observations. The sequence consists of t line_20: randomly placed over the 32 x 32 subgrid of the CCD. It is ho line_21: observations to further increase the accuracy of the relative line_22: stars through a bootstrap calibration developed procedure sug line_23: Eichhorn. ! question: 3 section: 2 line_1: Due to time limitations, three of the clustes are to be obser line_2: their centers. The outer regions are included in the observin line_3: priority 3 objects. The total observing time listed on the co line_4: that priority 3 objects will not be observed and that filter line_5: made during the 60 second read out of the CCD. line_7: Cycle 1 18.22 hours line_8: Cycle 2 0.45 hours line_9: Cycle 3 0.00 hours line_10: Cycle 4 0.00 hours line_11: Cycle 5 0.00 hours ! question: 4 section: 1 line_1: Ground based observations of the proper motions are limited b line_2: epoch plates, which usually have a very bright limiting magni line_3: addition, the poor seeing makes it impossible to observe near line_4: cluster and limits the positional accuracy to a value some 15 line_5: is possible with the PC. Since the difference in the position line_6: translates directly into a difference in the epoch difference line_7: wait at least 65 years for the second epoch on the ground. ! question: 5 section: 1 line_1: The only special scheduling requirements are to maintain the line_2: angle for all of the exposures in one sequence. This is neces line_3: have the same stars on all exposures. ! question: 6 section: 1 line_1: Sequence PC10 is used to obtain observations of the central r line_2: 6656 before and after the observations, which will hopefully line_3: during the first year of operations. The ten offset exposures line_4: obtain a bootstrap calibration of the spatial characteristics line_5: study the changes in the system over the observational period ! question: 7 section: 1 line_1: The data reduction will be done with the Astrometric Data Red line_2: Software developed by the Astrometry Team on computational fa line_3: available at the home institutions of the Team members. ! question: 10 section: 1 line_1: Computational facilities and the ADRS software package. ! question: 13 section: 1 line_1: Planetary Camera exposures will be taken of six of the globul line_2: (NGC 104, NGC 1851, NGC 6205, NGC 6656, NGC 6752, NGC 7078, N line_3: determine their internal motions from the horizontal branch t line_4: sequence. These motions will also be used to study the degree line_5: and isotropy in stars of differing masses.
