Appendix A: Presentation of the data

Tables presenting the data are given in this section.

Stars with U, B, and V magnitudes.

Table A.2

Catalogue of stars: R magnitudes.

Appendix B: The results

We present the results of the fits and all the two-color diagrams for zones 1 to 8. Table B.1 gives the slope of the linear regression for the different filters in the 8 zones. The normal slope is given in the last row. For a few zones and a few wavelengths, it is impossible to determine any reliable slope because of the too small number of data points. Table B.2 gives the correlation coefficient of the fit. Table B.3 gives the RV values deduced from Eq. (1). The last column gives the RV weighted mean value. The small thick segment at the bottom left of the plots is the locus of the unreddened O-B3 stars (from Martins et al. 2006; Koornneef et al. 1983; and Wegner 1994).
