RVO progress report (Dec 2010)
1. Working group "Technologies of RVO information structures"
(IPI RAS, led by Leonid Kalinichenko)
At the Institute of informatics problems of RAS the VO approaches
based on the mediation of heterogeneous distributed information
resources have been applied to the problem of calibration of
photometry of optical GRB afterglow. This problem has been formulated
by the Institute of Space Research of RAS. The ontology and conceptual
model of the respective application domain was defined. These
specifications, on the one hand, are absolutely independent on the
resources (catalogs) that might be chosen for the computations, and on
the other hand, they constitute a definition of the mediator. Several
catalogs were selected and registered at the mediator for creation of
an integrated database, including USNO, 2MASS, SDSS, VSX, UCAC, NSVS,
GSVC. The mediation infrastructure that includes AstroGrid inside,
allowed to formulate the problem declaratively in conceptual terms and
provided for the integrated access to the registered catalogs during
the computations.
Also at the Institute of informatics problems of RAS the subject
mediation infrastructure has been extended in the direction of stream
data processing support. The wrapper for accessing stream data sources
has been developed. With this extension the mediation infrastructure
becomes applicable to such problems as e.g. construction of light
curves of eclipsing variables, identification of a gravitational
microlensing event, etc.
2. The database of Moscow astronomical plate collection and
maintenance of the General Catalogue of Variable Stars (INASAN and SAI
MSU, led by Nikolai Samus)
We have prepared to submission the first of the three parts of the
80th Name-list of Variable Stars (2037 stars, among them 2019
variables at right ascensions from 0 to 6 hours and 18 rare-type
variables of the whole sky). Virtually ready is the second part of the
list (about 2200 stars in the RA range from 6 to 16 часов). In 2010,
GCVS names were immediately given to 8 Novae or rare-type variables.
We published a catalog of accurate equatorial coordinates for variable
stars in globular clusters (about 3400 stars in 103 clusters). A
completely revised GCVS version was compiled for the constellations of
Caelum and Camelopardalis (about 320 звезд); a similar work is under
way for Aquila (more than 1700 stars). We improved coordinates for
some 500 suspected variable stars from the NSV catalog and introduced
needed changes of the catalog spectroscopic and photometric data for
these stars. About 150 of the 500 stars lacked finding charts in the
literature; we have been able to find all but 2 of them; about 50 of
the stars were recovered by their variations in Internet-accessible
images of their fields. For a number of these stars, variability types
could be determined from observations available in automatic sky
surveys; these stars were selected for future Name-lists. We continued
comparison of positional information between the GCVS and the SIMBAD
databases; dozens of mistakes in both databases have been corrected.
The GCVS site remains a systematically updated web resource,
frequently used and widely cited. In 2010, we introduced about 2200
corrections into the database. Some 18500 visitors of the site were
recorded in 2010 (17% of them from the USA; 15%, from Russia; 6%, from
Japan), with about 48000 individual hits.
We continued digitizing the Moscow plate stacks using two CREO
EverSmart Supreme scanners. In 2010, we scanned 106 plates of the
Sternberg Institute's 40-cm astrograph (30?30 cm, 10?10 degrees) and
214 old plates (24?30 cm). By now, the total number of scanned plates
of the highest historical interest (the so-called S and T series, late
19th century to 1930s) exceeds 800; we also have scanned about 900
plates of the 40-cm astrograph. Beginning with mid-2010, we encounter
technical problems with the scanners. The final paper on our search
for variable stars in the 10?10-degree field centered at the star 66
Oph from scans of the 40-cm astrograph has been published. A total of
480 new variables were discovered and studied. We almost finished our
search for variables in the next field of the 40-cm astrograph,
centered at SA9, where we discovered 15 new variable stars. We
continued compiling an electronic catalog of plates and are virtually
ready with the old (S and T) plate series.
3. Working group "RVO data" (INASAN, led by Dana Kovaleva)
The list of original astronomical data resources created by Russian
investigators is maintained and regularly updated. The recent update
was done on September 2010. The total number of resources in the list
by this date came up to 180. The updated list will appear at the web
pages of RVO http://www.inasan.rssi.ru/eng/rvo/rus_res.html by the end
of 2010.
4. Zvenigorod Scanlaboratory Group (INASAN, led by Sergei Vereshchagin)
The process of Astrograph astroplates scanning has been continued.
In 2010 400 negatives was scanned. The fall of scanning speed connected
with transition to a new format (fits). Astrograph Zeiss-400 is
established in Zvenigorod Odservatory. It focus is 200 sm, lens
diameter is 40 sm. The plates size is 30 on 30 sm, wide field areas
of the sky equal 8 on 8 degrees.
The plates placing in a consecutive order was continued too.
3703 plates was laid in special boxes in the chronological
order according to observational log entries.
The version of a database with the list of plates is established
on server INASAN http://www.inasan.ru/rus/scan/ and
in WFDB - http://draco.skyarchive.org/search/search.cgi
