I have plotted NSVS and TASS data for the EA type star SU Boo using Bob Nelson's ephemeris HJD Min = 2452667.9434 + 1.56125 * E (http://binaries.boulder.swri.edu/omc/SU_Boo_OC.xls.htm). According to this ephemeris, SU Boo should have had an eclipse at JD 2453109.78. The TASS database shows it faint near JD 2453108.77 but not near JD 2453109.78. Adding 1 day to the JDs of the 5 data points concerned, gives a better fit to the ephemeris. Patrick __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!
