[vsnet-chat 2828] Re: Checking New Variables (Greaves)

[Seiichi Yoshida <comet@aerith.net>]

Dear Gianluca and colleagues,

I am Seiichi Yoshida working on the MISAO Project.

When we found candidates of new variable stars, we ourselves check
them in the database containing data in the GCVS 4.1, NSV, NSV Supl.,
and some other catalogs. The catalogs are available on the web, linked 
from the MISAO Project web page:

  http://vsnet.aerith.net/misao/doc/reference.html 

In addition, we also asked Kato-san to check them independently. After 
that, if no identification is found, we report them as MISAO's new
variable stars.

Many thanks to John Greaves for the TDF data. But as some pointed out,
it is impossible to check all known variable stars on the web
completely...

In case of MisV0719, it is clear that Gianluca is the first
discoverer, if Gianluca's web page had been open before late
1999. Thank you for your pointing, Gianluca. However, I will write a
paper on the MisV0719 and other MisV stars for the IBVS in the
future. In that case, what can I do? I guess I can only refer to the
URL of the Gianluca's web page, although it is not too good because
the contents of web pages can be changed or deleted. And I will write
something like, "MisV0719 is described as a variable star on Masi's
web page. We independently discovered the variability", although the
light curve was already obtained...

As Dr. Skiff wrote, it is very important to make many observations, 
create a light curve, and obtain the type, period, and some other
physical data. However, it is also important to put a number for a
star as a remark to show, "It is variable. It requires observations.",
especially now it is hard to collect all observations of all stars on
the all CCD images in the world. At the point of this view, I think it 
is better for variable star discoverers to publish their discoveries
as a catalog even if the light curve is not yet obtained. For example, 
if there is a catalog on the web, I can merge it to the MISAO database 
and obtain the data after this. Then sometimes many data will be
accumulated, many enough to obtain the physical data. 

Anyway, if the light curve was already obtained, as in case of
Gianluca, it is best to submit IBVS on the result. When the star was
designated by the GCVS members, the IBVS paper will be referred. Then, 
even if the MISAO's paper will be also referred, people can know that 
Gianluca is the best contributor to the star.

Best regards,
