Abstract:
  Differential Stromgren uvby photometric observations from the Four
  College Automated Photoelectric Telescope of four magnetic Chemically
  Peculiar stars are used to refine rotational periods and to define the
  shapes of the light curves.  HR 1643 (P = 2.73475 d) shows large phase
  variability in all four magnitudes.  Theta Aur (P = 3.6188 d) exhibits
  large amplitude variations with two components contributing to the
  minima.  For 49 Cam (P = 4.28679 d), we probably are observing both
  polar regions and much of the surface.  The values for HR 3724 (P =
  33.984 d) confirm Wolff's result that the main variability is in v.

Description:
  The table files are accompanied by text files that contain yearly
  means and standard deviations for each magnitude as well as ensemble
  means.  (Originally, these yearly means were presented within the data
  tables following each years observations.  This made the data tables
  difficult to document consistently and would make them impossible to
  convert to FITS tables.  The means were moved to separate files and
  the Heliocentric Julian Date of the first and last observation for the
  given means were added.)

Notes for file: table2.txt table3.txt table4.txt table5.txt
--------------------------------------------------------------------------------
Text:
  The text file gives means and standard deviations as described above.
  For example:

  year 2  2448531.9511 to 2448605.8525
  average      -0.738  2.028 -0.480  1.921 -0.419  1.862 -0.378  1.866
  std. dev.     0.038  0.007  0.017  0.005  0.016  0.004  0.014  0.007

  The numbers following "year 2" in this example are the Heliocentric
  Julian Date of the first and last observations for the year in
  question.  The columns following "average" and "std. dev." are the
  v-c and ch-c magnitudes for u, b, v, and, y as described for the
  data tables above.
