This directory contains: README - this file he1104.dat - file with photometry of the gravitational lens HE1104-1805 collected during the OGLE survey. The columns contain: (1) Heliocentric Julian Date - 2450000, (2) magnitude of image Q_A, (3) error of magnitude of Q_A, (4) magnitude of image Q_B, (5) error of magnitude of Q_B, (6) magnitude of comparison star (A), (7) error of magnitude of comparison (A). All observations were obtained through V-band filter. The zero point of photometry is defined as the average magnitude of comparison stars A and B. Magic number 9.999 means "no data".
