1 Introduction

Published values of [Fe/H] are now available for more than 1000 evolved G and K stars. If those data are to be as useful as possible, it is desirable to reduce them to a common zero point, average them, and present the averages in a catalog with corresponding rms errors. This paper is the fourth in a series that considers such a catalog. In the three preceding papers, the analysis used to produce the catalog data has been described (see Taylor 1998a,b, 1999). This paper describes the catalog itself and an auxiliary catalog of derived stellar temperatures.
