A Revised Photometric Sequence and a Reconnaissance of the Surrounding Field Population Walker, Alistair R. Abstract A photometric sequence consisting of 53 stars measured in the V, B, and I bands has been set up in the vicinity of the rich, young Large Magellanic Cloud cluster, NGC 1866. Many of these stars are relatively isolated and are thus suitable for use as local standard stars for photometric studies of the cluster. Color magnitude diagrams to a limit of V = 20.5 for various parts of the 13 x 13 arcmin field, centered on the cluster, show that NGC 1866 is embedded in a mix of populations which includes stars younger than the cluster itself, the dominant 0.5-3 Gyr population, plus some very old stars represented by four RR Lyrae variables.
