Description:
We report 8 years of previously unpublished photometric observations
of FK Com. The observations have been carried out between 1993 and
2001 with six different telescopes: 60 cm at Mt. Maidanak (Tashkent,
Uzbekistan), Phoenix 10, Wolfgang and Amadeus located in Arizona, USA,
and 20cm and 60 cm KVA on La Palma, Spain. Observations contain
measurements at the following bands: Johnson U, B, V and R, Bessel R,
Cousins I and Stromgren b and y. The observations are differential
photometry in respect to the primary comparison star HD 117567.
NOTE: Table 1 in the paper contains some small misprints in the Julian
dates. Also for Wolfgang and Amadeus the number of observations given
in Table1 at each band is slightly less than actually given in Table2c
and Table2d. This is caused by accidentally using a limiting error of
0.01 in magnitudes when creating Table 1. In Table 2 the limiting
error for Wolfgang and Amadeus is 0.02 mag, as mentioned in the paper
itself. In Table2a-e 99.0000 means that no observations were available
at that time at that band or that the error in the magnitude was
larger than 0.02.
