Description:
All tables contain the results of the spectral and photometric
observations of the symbiotic star LL Cas. Observations were carried
out within 1986-2006 with a slit spectrograph attached to the 0.7-m
telescope of the Fessenkov Astrophysical Institute (Almaty,
Kazakhstan). Some photoelectric observations of LL Cas with broad-band
filters were carried out on a photoelectric polarimeter mounted on the
1-m Zeiss telescope (Assy-Turgen, Kazakhstan).
