Description:
   Summaries are presented of the photoelectric measurements of
   stellar CaII H and K line intensity made at Mount Wilson
   Observatory during the years 1966 - 1983. These results are
   derived from 65,263 individual observations of 1296 stars. For
   each star, for each observing season, the maximum, minimum, mean,
   and variation of the instrumental H and K index "S" are given, as
   well as a measurement of the accuracy of observation. A total of
   3110 seasonal summaries are reported.
   Factors which effect the ability to detect stellar activity
   variations and accurately measure their amplitudes such as the
   accuracy of the H and K measurements and scattered light
   contamination are discussed. Relations are given which facilitate
   intercomparison of "S" values with residual intensities from
   ordinary spectrophotometry, and for converting measurements to
   absolute fluxes.
