al. ([@mola98]). The UIT image of NGC 2808 was a 979 second exposure obtained on 19 May 1995 using the B1 filter, which has a central wavelength of 1520 Å and a width of 350 Å. The FWHM of the star images was about 5 and the faintest hot HB stars were near the sensitivity limit. Therefore, to create an ultraviolet colour-magnitude diagram, we performed 3-pixel (34) radius circular aperture photometry only on isolated stars (all more than 2 from the cluster center) which had a positional match with hot ($B-V <$ ) stars in the catalogs of Walker ([@walk99]) or Bedin et al. ([@bepi00]). A star was determined to be isolated if it had no neighbours within 5 on either the UIT image, or on the lists of hot stars in the optical catalogs. We used the standard UIT absolute calibration and determined an aperture correction of using a few isolated UV-bright stars. The resulting UIT colour-magnitude diagram obtained from the 1520 Å photometry given in Table \[ngc2808\_par\] is shown in Fig. \[uitcmd\], and includes all our spectroscopic targets except for W26607 which has a blurred PSF on the UIT image. The complete ultraviolet photometry and optical identifications used
