Figure 2: Fits to the Hyades MS. All 3 plots show the Hyades single star data (open triangles) and polynomial fit to the MS line, both shifted in magnitude by the best-fit distance modulus, and the field star data at their absolute magnitudes (filled circles). Top panel - V/(V-K) CMD, using best-fit distance modulus of (m-M)_{0}=3.33; middle and bottom panels - K(J-K) CMDs, showing shifted and unshifted field stars using best-fit distance moduli of (m-M)_{0}=3.40 and (m-M)_{0}=3.35 respectively. | |

Figure 3: Fits to dereddened and extinction corrected M 67 MS - symbols as for Fig. 2. Top panel - V/(V-K) CMD, using best-fit distance modulus of (m-M)_{0}=9.65; middle and bottom panels - K(J-K) CMD, showing shifted and unshifted field stars, using best-fit distance moduli of (m-M)_{0}=9.63 and 9.61, respectively. | |

Figure 4: Fits to dereddened and extinction corrected Pleiades MS - symbols as for Fig. 2. Top panel - V/(V-K) CMD, using best-fit distance modulus of (m-M)_{0}=5.67; middle and bottom panels - K(J-K) CMD, shifted and unshifted field stars respectively, both using best-fit distance modulus of (m-M)_{0}=5.61. | |
