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

http://quasars.org/milliquas.htm

and on NASA HEASARC at

https://heasarc.gsfc.nasa.gov/W3Browse/all/milliquas.html

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.

Richard

[[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
http://ruina.tam.cornell.edu/research/topics/miscellaneous/push-me_pull-you.pdf
) is more appropriate for our sister newsgroup sci.physics.research.
