Hi Valentin (and Chandreyee),

I write you because I am going through all the VMC papers to see which tables would be best to include with DR7.

I concluded that having one table with the VMC parameters and the spectroscopic ones for the confirmed quasars would be a valuable addition.

Such a table would contain about 300 sources as follows.

  • 117 known quasars from Cioni et al. 2013 (table 2)
  • 37 confirmed quasars from Ivanov et al. 2016 (table 1 and table 2 merged)
  • 136 confirmed quasars from Ivanov et al. 2023 (table 1 and table 4 merged)
  • 6 confirmed quasars from Maitra et al. 2019 (table A.1 and A.3 merged)

The format of a single table would be:

Name, Ra, Dec, Y, sigma_Y, J, sigma_J, Ks, sigma_Ks, class, spectral features with wavelengths, redshift+error.

This information is available already in the publications, but in separate tables. Only for the 6 quasars the paper gives VMC colours, but not magnitudes (as these are very few objects, it should be easy to find those from the VSA).

I addressed this email to Valentin because Chandreyee is on leave and Nick is in cc such that he knows that there will be a table for confirmed quasars.

Would you have time to prepare a combined table for Nick? Best would be next week, but if you need more time let me know!
