Abstract (from CDS):

We have conducted a deep (15≲r≲23), 20 night survey for transiting planets in the intermediate-age open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD camera on the 6.5 m MMT. In this paper we describe the observations and data reduction procedures for the survey and analyze the stellar content and dynamical state of the cluster. By combining high-resolution spectroscopy with existing BVICKs and new gri color-magnitude diagrams, we determine the fundamental cluster parameters: t=485±28 Myr without overshooting (t=550±30 Myr with overshooting), E(B-V)=0.227±0.038, (m-M)V=11.57±0.13, and [M/H]=+0.045±0.044, which are in good agreement with, although more precise than, previous measurements. We determine the mass function down to 0.3 M☉ and use this to estimate the total cluster mass of 3640±170 M☉.
