Description

Context The RAVE dataset along with Gaia DR1 was used by Zackrisson et al. (2018), a paper on Dysonian SETI. Gaia is a mission of the European Space Agency (ESA) that aims to accurately measure the position, distance and magnitude of over a billion stars. RAVE is a radial velocity dataset. RAVE also provides spectrophotometric parallax data, as well as cross-identification of stars with a number of other datasets, including Gaia DR2. Content This dataset is a combination of RAVE DR5 and Gaia DR2 sources. The data is obtained using the query tool of the RAVE project. The SQL query follows: SELECT G.source_id,G.parallax,G.parallax_error,G.ra,G.dec,G.phot_g_mean_mag,G.phot_bp_mean_mag,G.phot_rp_mean_mag,G.l,G.b,G.pmra,G.pmdec, R.HRV AS r_hrv,R.Met_K AS r_metallicity,R.Algo_Conv_K AS r_quality,R.Mg AS r_mg,R.Si AS r_si,R.Ti AS r_ti,R.Fe AS r_fe,R.Ni AS r_ni,R.distance r_distance,R.parallax r_parallax,R.Jmag_2MASS r_jmag_2mass,R.Hmag_2MASS r_hmag_2mass,R.Kmag_2MASS r_kmag_2mass, R.RAdeg r_ra,R.DEdeg r_de, W1mag_ALLWISE r_w1mag_allwise, W2mag_ALLWISE r_w2mag_allwise, W3mag_ALLWISE r_w3mag_allwise, W4mag_ALLWISE r_w4mag_allwise, BTmag_TYCHO2 r_btmag_tycho2, VTmag_TYCHO2 r_vtmag_tycho2, Bmag_APASSDR9 r_bmag_apassdr9, Vmag_APASSDR9 r_vmag_apassdr9, rpmag_APASSDR9 r_rpmag_apassdr9, ipmag_APASSDR9 r_ipmag_apassdr9, Imag_DENIS r_imag_denis, Jmag_DENIS r_jmag_denis, Kmag_DENIS r_kmag_denis, B1mag_USNOB1 r_b1mag_usnob1, R1mag_USNOB1 r_r1mag_usnob1, B2mag_USNOB1 r_b2mag_usnob1, R2mag_USNOB1 r_r2mag_usnob1, Imag_USNOB1 r_imag_usnob1 FROM RAVEPUB_DR5.RAVE_DR2gaia_source G INNER JOIN RAVEPUB_DR5.RAVE_DR5 R ON R.RAVE_OBS_ID=G.RAVE_OBS_ID WHERE G.parallax IS NOT NULL

The following processing was done:

Removed rows with missing values in any of the following columns: "ra",

       "dec",
       "pmra",
       "pmdec",
       "l",
       "b",
       "parallax",
       "parallaxerror",
       "photgmeanmag",
       "photbpmeanmag",
       "photrpmeanmag",
       "rhrv",
       "rmetallicity",
       "rdistance",
       "rparallax",
       "rjmag2mass",
       "rhmag2mass",
       "rkmag2mass",
       "rmg",
       "rsi",
       "rfe",         
       "rquality",
       "rra",
       "rde",
       "rw1magallwise",
       "rw2magallwise",
       "rw3magallwise",
       "rw4magallwise",
       "rbmagapassdr9",
       "rvmagapassdr9",
       "rrpmagapassdr9",
       "ripmagapassdr9",
       "rimagdenis",
       "rjmagdenis",
       "rkmagdenis"

Averaged those values for rows that have the same Gaia "source_id".

Note An alternative dataset is recommended: 257k Gaia DR2 stars. It contains sources from the Northern and Southern Hemispheres.
