Abstract:
We present new multicolour (U,B,V,Rc,Ic) photometric observations of
classical symbiotic stars, EG And, Z And, BF Cyg, CH Cyg, CI Cyg,
V1329 Cyg, TX CVn, AG Dra, Draco C1, AG Peg and AX Per, carried
out between 2007.1 and 2011.9. The aim of this paper is to present
new data of our monitoring programme, to describe the main features
of their light curves (LC) and to point problems for their future
investigation. The data were obtained by the method of the classical
photoelectric and CCD photometry.
Description:
The tables contain photoelectric U, B, V and CCD U, B, V, Rc, Ic
observations of symbiotic stars EG And, Z And, BF Cyg, CH Cyg, CI Cyg,
V1329 Cyg, TX CVn, AG Dra, Draco C1, AG Peg and AX Per. Each value
represents the average of the observations during a night. The inner
uncertainty of this night-means is of a few times 0.01 mag in the
B,V,Rc and Ic bands, and up to 0.05mag in the U band.
