Abstract:
The prototype version of the Korean Astronomical Data Center (KADC)'s database
server is presented. The first dataset is from the Bohyunsan Optical Astronomy
Observatory (BOAO)'s 1.8m optical telescope. The total amount of the data is
about 400 GB and these data are obtained during 1997 Sep - 2002 Dec
by using 1K CCD, 2K CCD, and medium-dispersion spectrograph.
The prototype version of KADC database has two modes for the users : (i) user
can look through the list of titles of observing runs, observation logs, and
parameters of each FITS files, and (ii) user can search data by typing object
name, coordinates and search box size, etc. The FITS format files for target
objects together with all accompanying files for processing can be obtained.
In KADC database, the search process is being operated by SQL using
metadata-table which contains information of FITS header parameters.
This archive is the first astronomical database made in Korea,
which will be expanded for the Taeduk 14m radio telescope data and
future projects such as Korean VLBI Network (KVN, to be completed in 2007)
and 8m-class large optical telescope which is currently being designed.
The Korean Astronomical Data Center
(KADC)
was established in 2002 as a new department in Korea Astronomy Observatory
(KAO),
the national observatory of the Republic of Korea, and
has performed the principal axis in giving birth to the Korean Virtual Observatory
(KVO)
in February 2003
(Kim et al. 2003).
As a first mission of the KADC/KVO, we are building databases of
astronomical data produced by telescopes in Korea.
In this paper, we introduce the prototype version of KADC using the
Bohyunsan Optical Astronomy Observatory
(BOAO)
1.8m optical telescope data.
BOAO is located at the summit of Mt. Bohyun, south-eastern part of Korea,
at the altitude of 1,162m. It is founded on April 1996 and has 1.8m
reflecting telescope (Figure 1) as the main facility.
Using the
400 GB data obtained by this telescope during 1997 September
to 2002 December, we have constructed an archive.
The database is consisted of photometric (using 1K CCD and 2K CCD) and
spectroscopic (using medium-dispersion spectrograph) data
and the number of FITS files exceeds 80,000.
The first web service is being made by 1997 to 2001 data.
Figure 2 shows the main page of this BOAO data archive.
Primary search criterion of object name or coordinates (with search box size)
can be used to search for the data, and
secondary optional search criteria of observation date, observer(s),
data type, and/or instrument are also useful for obtaining concrete data.
The search process is being operated by SQL using
metadata-table which contains information of FITS header parameters.
There are also JPG images for preview and re-sorting options for
each table column are provided.
Figure 3 shows a sample of search result page, from where the data
can be uploaded to the FTP site
for further downloading in FITS format (Figure 4).

The current prototype version of KADC will be expanded to contain the data
produced by other Korean telescopes,
such as those obtained from Taeduk 14m radio telescope,
YSTAR (Yonsei Survey Telescopes for Astronomical
Research)-NEOPAT (Near Earth Object PATrol) project, and Galactic plane CO
survey (
) project using the Seoul National University 6m radio telescope.
Data from telescopes that will be built in the near future (e.g., Korean
VLBI Network; KVN) and data from satellites launched by international
cooperation (e.g., Far-ultraviolet IMaging Spectrograph (FIMS), Galaxy
Evolution Explorer (GALEX)) will also be used.
