[vsnet-chat 7461] CRTS transients, names

   This is related to one of my central questions.  Although these
ATELs are indeed linked by ADS, they have no "SIMBAD Objects" entries
for CRTS objects.  Why?  This lack of SIMBAD reference is (in practice)
one of the main difficulties in referring to CRTS discovery announcements
properly.

   This appears to be true for a more solid publication, e.g.
http://adsabs.harvard.edu/abs/2009ApJ...696..870D
"First Results from the Catalina Real-Time Transient Survey"
and click on "SIMBAD Objects".

   An interesting case would be "SDSS J102146.44+234926.3".
There have been two papers dealing with this object with this name.
This object
http://adsabs.harvard.edu/abs/2006CBET..746....1C
was discovered by E. J. Christensen during the course of the Catalina
Sky Survey, but not an SDSS CV.  I wonder why there wasn't a question how
the discovery can be more correctly reflected on the nomenclature.
(I've heard that the CSS team and the CRTS team are different in entity,
so the policies might have been different, even if the discoveries are
from the same source material).

   Perhaps variable star folks are a bit too inclined to "own their own
variable stars".  (Remember that the MISAO project assigned MisV1436
to the already known quasar QSO B0133+47; some of Takamizawa variables
were IRAS-selected variable stars etc.)

   The devil (?) is also in the detail in professional works...
Accodring to http://www.astronomerstelegram.org/?read=2086
"CSS090530:144011+494734 was found to have superhump period 0.06474d by
Miller et al. 2009 (vsnet-alert 11283)."
The discoverer of the superhumps was David Boyd (vsnet-outburst 10293 =
vsnet-alert 11279) and Miller was not the top author of vsnet-alert 11283.
This single incident is sufficient to tell how difficult it is to
correctly credit original information.
