Extrasolar Planet Transit Light Curves and a Method to Select the Best Planet Candidates for Mass Follow-up

A unique analytical solution of planet and star parameters can be derived from an extrasolar planet transit light curve under a number of assumptions. This analytical solution can be used to choose the best planet transit candidates for radial velocity follow-up measurements, with or without a known spectral type. In practice, high photometric precision (< 0.005 mag) and high time sampling (< 5 minutes) are needed for this method. See Seager & Mallen-Ornelas (2002) for full details.
