ABSTRACT:
LINE_1:The globular clusters Omega Centauri and 47 Tucanae will be observed
LINE_2:with the "B" and "V" filters of the FOC f/96.  An 80-min total in each
LINE_3:color will reach well down the main sequence in each cluster, to
LINE_4:fainter limiting magnitude than ground-based observations, in central
LINE_5:regions that ground-based observations cannot resolve  at all.  Three
LINE_6:FOC fields will be observed in each cluster: at the center, and one and
LINE_7:three core radii out.  One main objective is to observe the
LINE_8:radial distributions of main-sequence stars of different mass, so as
LINE_9:to determine the degree of equipartion at the center of each cluster.
LINE_10:Along with this goes the luminosity function of the same stars.  Another
LINE_11:objective is to carry the CMD and luminosity functions as faint as
LINE_12:possible.  Also, the top of the white-dwarf sequence should be
LINE_13:observable.
LINE_14:
LINE_15:This is a repeat of a program taken with the aberrated HST; it should
LINE_16:now be possible, in these crowded regions, to go 3 to 5 magnitudes
LINE_17:fainter.

 QUESTION:  3
  SECTION:  1
LINE_1:In each cluster, 3 FOC fields are observed with f/96.  Exposure times:
LINE_2:
LINE_3:  (for each of 3 fields) F430W, 80M; F480LP, 80M.
LINE_4:
LINE_5:Note that for NGC 104 (exp. lines 2-7) all exposures can be taken
LINE_6:with a single guide-star acquisition.
 QUESTION:  4
  SECTION:  1
LINE_1:Only HST can penetrate the centers of globular clusters to a faint
LINE_2:limiting magnitude.  These clusters have already been pushed as far
LINE_3:as they can be with the aberrated HST, and it is now time to do them
LINE_4:more deeply.
 QUESTION:  5
  SECTION:  1
LINE_1:NGC 104 (exp. lines 2-7) can be taken on a single guide-star acquisition.
LINE_2: This is not a scientific requirement but will save spacecraft time.
LINE_3:Also, this object is at times in the continuous-viewing zone.
