Overview
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission will search for terrestrial planets in the habitable zone of solar-type stars. Because of telemetry limitations, PLATO targets need to be pre-selected. We present an all sky catalog that will be fundamental to select the best PLATO fields and the most promising target stars, derive their fundamental parameters, analyze the instrumental performances, and then plan and optimize follow-up observations. This catalog also represents a valuable resource for the general definition of stellar samples optimized for the search of transiting planets. The first public release of the all sky PLATO Input catalogue (asPIC version 1.1) contains a total of 2,675 ,539 stars, among which are 2,378,177 FGK dwarfs and subgiants and 297,362 M dwarfs. It was produced using Gaia Data Release 2 (DR2) astrometry and photometry and 3D maps of the local interstellar medium.
