Brown dwarfs in the Pleiades cluster

We present the results of a deep CCD-based IZ photometric survey of a ~ 1 deg2 area in the central region of the Pleiades Galactic open cluster. The magnitude coverage of our survey (from $I\,\sim\,17.5$ down to 22) allows us to detect substellar candidates with masses between 0.075 and 0.03 $M_{\od...

Zusammenfassung:	We present the results of a deep CCD-based IZ photometric survey of a ~ 1 deg2 area in the central region of the Pleiades Galactic open cluster. The magnitude coverage of our survey (from $I\,\sim\,17.5$ down to 22) allows us to detect substellar candidates with masses between 0.075 and 0.03 $M_{\odot}$. Details of the photometric reduction and selection criteria are given. Finder charts prepared from the I-band images are provided.
