The light curves are analyzed using a binary star model based on Roche geometry to fit the photometric observations. Spectroscopic parameters, such as the mass ratios and spectral types, were taken from recent spectroscopic studies of the systems in question. Description: The files contain CCD photometric observations of the close binaries QX And, RW Com, MR Del and BD +07 3142, obtained with the Apogee ALTA U47 CCD camera attached to the 40cm Schmidt-Cassegrain telescope located at the Ankara University Observatory (AUG) by using BVR filters in close accordance with the Johnson-Cousins standard system Objects: ---------------------------------------------------------- RA (2000) DE Designation(s) ---------------------------------------------------------- 01 57 57.8 +37 48 23 QX And = V* QX And 12 33 00.3 +26 42 58 RW Com = V* RW Com 20 31 13.5 +05 13 09 MR Del = V* MR Del 16 20 03.2 +07 07 29 BD +07 3142 = AG+07 2032 ---------------------------------------------------------- File Summary:
