Abstract

We derive an intrinsic colour calibration for FK stars using broad band Johnson colours and line indices KP and HP2. Through this calibration we can deter mine 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 Stromgren photometry through the Schuster & Nissen (1989) calibration. The agreement is also good with the reddening maps of Burstein & Heiles (1982) and Schlegel et al. (1998), although in this case there exists a small offset of about 0.01 mag. This calibration may be applied to the large body of data ofthe HK survey extension which will be published in the near future.
