Notes. The EROS microlensing targets (Col. 1) with the ranges in right ascension and declination, the number of fields, the number of exposures, the total number of cataloged stars, and the number of stars with a photometric precision in Beros lower than 0.1mag. Columns 8 and 9 list the approximate EROS magnitudes corresponding to a precision of 0.1 mag, and Cols. 10 and 11 list the approximate magnitude limits containing 90% of the stars. The precise values of the EROS-2 magnitudes depend on the field because of differences in exposure time and stellar density. The magnitudes for the EROS-1-Schmidt-Plates magnitudes are for objects outside the LMC bar.
