1 Landolt BV and Sloan gri photometry of 358,963 RAVE stars Ulisse Munari and Arne Henden

2 239,102 RAVE stars have a Tycho-2 counterpart 377,807 stars have a match in DENIS

3 399,443 RAVE stars have a 2MASS counterpart err(J)=0.023 err(H)=0.032 err(K)=0.026

4 G0 main sequence dwarfRAVE to date, 358,963 RAVE stars have been observed by APASS on at least 2 distinct epochs in the Landolt B,V and Sloan gri bands. median of internal errors of the mean on RAVE stars: 0.013 0.011 0.012 0.013 0.018 mag

5 on average 3.7 epochs target 6 epochs

6 median 0.274 arcsec

7 Landolt (1983, 1992) primary standards

8 Henden and Munari (2000, 2001, 2006) seconday Landolt standards

9 Smith et al. (2002) secondary SLOAN standards

10 Mermilloid (1992)

11 Hartman et al. (2008)

17 - BVgri support photometry from APASS now available for 358,963 RAVE stars (and counting) - median value for the error of the means about 0.013 mag - no offset/trend and rms=0.025 on Landolt/Sloan photometric standards, about the same as 2MASS JHKs data - rms of derived photometric temperatures 250 K - no significant offset with Greg/Jon spectroscopic temperatures from high res APO Echelle observations of 571 well distributed RAVE stars SUMMARY - extention toward V=7.5 stars started (essential for accessing the bulk of spectroscopic calibrators) - inclusion of zY band will start soon - pilot survey of 100 sq.deg in u band completed - analysis of APASS data of PASTEL stars not yet completed but so far promising
