Photometric study of selected cataclysmic variables. II. Time-series photometry of nine systems. Papadaki C., Boffin H.M.J., Stanishev V., Boumis P., Akras S., Sterken C. <The Journal of Astronomical Data, 15, 1 (2009)> =2009JAD....15....1P
ADC_Keywords: Binaries, cataclysmic ; Photometry Abstract: We present time-series photometry of nine cataclysmic variables: EI UMa, V844 Her, V751 Cyg, V516 Cyg, GZ Cnc, TY Psc, V1315 Aql, ASAS J002511+1217.2, V1315 Aql and LN UMa. The observations were conducted at various observatories, covering 170 hours and comprising 7850 data points in total. For the majority of targets we confirm previously reported periodicities and for some of them we give, for the first time through photometry, their underlying spectroscopic orbital period. For those dwarf-nova systems which we observed during both quiescence and outburst, the increase in brightness was accompanied by a decrease in the level of flickering. For the eclipsing system V1315 Aql we have covered 9 eclipses, and obtained a refined orbital ephemeris. We find that, during its long baseline of observations, no change in the orbital period of this system has occurred. V1315 Aql also shows eclipses of variable depth.

Note (1): For fig4.dat, each night's light curve was brought around its nightly mean magnitude. Each light curve, is therefore shifted by this amount.
