Pre-FLAMES Survey: Observations of Selected Stellar Fields

This paper presents the first set of fully calibrated images and associated stellar catalogs of the Pre-FLAMES survey being carried out by the ESO Imaging Survey (EIS) project. The primary goal of this survey is to provide the ESO community with data sets from which suitable target lists can be extracted for follow-up observations with the new VLT facility FLAMES. For this purpose 160 stellar fields have been selected for observations in B, V and I using the 8kx8k Wide Field Imager (WFI) at the MPG/ESO 2.2 m telescope at La Silla. These data have been used to assess the observing strategy adopted and to define suitable reduction techniques and procedures for the preparation of input catalogs for FLAMES. The images and catalogs presented here are publicly available and can be requested from the URL address ``http://www.eso.org/eis''.
