VizieR Online Data Catalog: Main-sequence A, F, G, and K stars photometry (Boyajian+, 2013)

Akin to the observing outlined in DT1 and DT2, observations for this project were made with the CHARA Array, a long-baseline optical/infrared interferometer located on Mount Wilson Observatory in southern California. The target stars were selected based on their approximate angular size (a function of their intrinsic linear size and distance to the observer). We limit the selection to stars with angular sizes >0.45mas, in order to adequately resolve their sizes to a few percent precision with the selected instrument setup. Note that all stars that meet this requirement are brighter than the instrumental limits of our detector by several magnitudes. The stars also have no known stellar companion within 3-arcsec to avoid contamination of incoherent light in the interferometers' field of view. From 2008 to 2012, we used the CHARA Classic beam combiner operating in the H band (λ_H=1.67um) and the K' band (λ_K'=2.14um) to collect observations of 23 stars using CHARA's longest baseline combinations.
