For the present survey we selected 92 Harvard variable Cepheids spread over the SMC. These objects have all been extensively studied over the years; archival optical and/or near-IR data is available for all of them and the vast majority were measured by OGLE (Udalski et al. 1992, 1997; Soszynski et al. 2010).Ninety fundamental mode SMC type I (and two type II) Cepheids were observed with Spitzer between 2010 August and 2012 January (Program ID 70010, P.I. Madore). Each light curve has 12 epochs, each spaced by approximately P/12 days, where P is the Cepheid's pulsation period.(2 data files).
