Notes. Column 1. Name/identifiers. CEP0227 refers to OGLE-LMC-CEP-0227, etc. T2C098 refers to LMC-T2CEP-098. CEP1718 appears twice as both components of the EB are Cepheids. Column 2. FM Period. For the first overtone (FO) pulsators the conversion is outlined in Pilecki et al. (2018). Columns 3–7: Stellar parameters of the cepheid: mass, gravity, effective temperature, luminosity and radius. Column 8. Projection factor when available. Column 9. Remarks, indicating which Cepheids are FO pulsators. All data from Pilecki et al. (2018).
