Brown Dwarfs in the Pleiades Cluster. III. A deep IZ survey

We present the results of a deep CCD-based IZ photometric survey of a similar to 1 deg(2) area in the central region of the Pleiades Galactic open cluster. The magnitude coverage of our survey (from I similar to 17.5 down to 22) allows us to detect substellar candidates with masses between 0.075 and 0.03 M.. Details of the photometric reduction and selection criteria are given. Finder charts prepared from the I-band images are provided.
