Introduction 1.1 Purpose The Stellar Classification Program (SCP) for the Kepler Mission is responsible for preparing the Kepler Input Catalog (KIC) for delivery to the Science Office (SO) before 1 January 2008. The results of new multi-band ground-based photometry and spectroscopy being carried out by the SCP team will be combined with existing information for all known objects in the Kepler Field of View (FOV) to create the KIC. The Kepler SO will use the information in the KIC when selecting targets to be observed by Kepler. 1.2 Scope This plan applies from Phase B through launch of the Kepler spacecraft.Stellar Classification Program Plan KSCP-15005-002 3 August 2006 8 of 13 2. Driving Requirements The SCP tasks are determined by specific requirements flowing down from the Kepler Ground System Requirements Document (GSRD). The requirements are listed below. 2.1 GSRD Requirements • GSRD174: The Stellar Classification Program (SCP) shall prepare and deliver the Kepler Input Catalog prior to the launch for the purpose of selecting planetary target stars. The SCP activity addressing this requirement is discussed in Section 4.5. • GSRD175: Prior to launch the SCP shall identify and catalog the coordinates, brightnesses, and stellar radii of ≥ 150,000 of the brightest targets in the active FOV with a radius ≤ 2 solar radii. The SCP activity addressing this requirement is discussed in Sections 3.1 and 5. • GSRD176: The SCP shall determine stellar radii to an uncertainty of less than 50%. The SCP activity addressing this requirement is discussed in Section 5. • GSRD357: The Ground Segment shall plan to operate the FS (Flight Segment) with the photometer axis pointed near Right Ascension of 19h23m and Declination of +44°30'. The SCP activity addressing this requirement is discussed in Section 3.1.Stellar Classification Program Plan KSCP-15005-002 3 August 2006 9 of 13 3. Photometry In November 2002 the Kepler Science Team recommended that a new ground-based multi-band photometric survey be carried
