Scientific paper

In the paper we report the discovery of a new variable star, called S10947 Aql, as the likely optical counterpart of RX J2009.8+1557. The optical variability pattern as well as the detected X-ray emission suggest that it is a chromospherically active binary of the RS Canum Venaticorum type. We discovered an occasional disappearance of the eclipsing minima as well as large variations in the eclipse amplitude. The present file contains the full set of measurements from the various types of the 705 photographic plates used in this investigation (note that the number of 709 given in the paper is wrong). The table file is sorted according to plate type which is listed in the first column. Given for each measurement are the Julian Date (corresponding to the time of mid-exposure) and the photographic magnitude. Uncertain measurements and/or upper limits are marked with a flag (4th column). (1 data file).
