Default Milliquas v5.2 includes SDSS DR14

The Million Quasars (Milliquas) catalogue presents a new release,
v5.2, which includes just-published SDSS-DR14 and SDSS-DR14Q data.
The count of type-I quasars & AGNs is now over 607,000. Milliquas now
also includes ~435,000 WISE quasar candidates over the whole sky, with
photometric redshifts calculated by me using the 4-colour method
documented in Flesch 2015,PASA,32,10. The catalogue's total count of
quasars, candidates and misc objects is just shy of 2 million..

The catalogue and ReadMe (which documents all this) are available on


and on NASA HEASARC at


and are expected to be available on VizieR soon.

This may well be my last data release as SDSS DR15 is due out in July
2019, i.e. another 2 years, and I don't plan any Milliquas releases
before then. Two years is a long time and maybe I won't come back to
it then. But I'll post here now and again -- maybe on some
controversial topic like in the old days, who knows.

cheers, Eric

Yes Eric, there was a time when weeks and multiposts
addressed such arcane but interesting topics
such as 'faster than wind'
Now the boundaries of discourse seem to be unnecessarily constrained.


[[Mod. note -- I think the topic of 'faster than wind' (a.k.a considering
whether a suitable sailboat with both water & air propellers can sail
downwind in still water faster than the wind velocity, as in
) is more appropriate for our sister newsgroup sci.physics.research.
