Intrinsic colour calibration for F, G, K stars.

BONIFACIO P., CAFFAU E. and MOLARO P.

Abstract (from CDS):

We derive an intrinsic colour calibration for F-K stars using broad band Johnson colours and line indices KP and HP2. Through this calibration we can determine E(B-V) of an individual star within 0.03 mag. The E(B-V) values thus derived are in excellent agreement with those derived from Stroemgren photometry through the Schuster & Nissen (1989A&A...221...65S) calibration. The agreement is also good with the reddening maps of Burstein & Heiles (1982AJ.....87.1165B) and Schlegel et al. (1998ApJ...500..525S), although in this case there exists a small offset of about 0.01mag. This calibration may be applied to the large body of data of the HK survey extension which will be published in the near future.
