Abstract:
In 2008 January the twenty-fourth Chinese expedition team successfully
deployed the Chinese Small Telescope ARray (CSTAR) to Dome A, the
highest point on the Antarctic plateau. CSTAR consists of four 14.5cm
optical telescopes, each with a different filter (g,r,i, and open) and
has a 4.5°x4.5° field of view (FOV). It operates robotically
as part of the Plateau Observatory, PLATO, with each telescope taking
an image every ∼30s throughout the year whenever it is dark. During
2008, CSTAR 1 performed almost flawlessly, acquiring more than 0.3
million -band images for a total integration time of 1728hr during 158
days of observations. For each image taken under good sky conditions,
more than 10,000 sources down to magnitude could be detected. We
performed aperture photometry on all the sources in the field to
create the catalog described herein. Since CSTAR has a fixed pointing
centered on the south celestial pole (Dec=-90°), all the sources
within the FOV of CSTAR were monitored continuously for several
months. The photometric catalog can be used for studying any
variability in these sources, and for the discovery of transient
sources such as supernovae, gamma-ray bursts, and minor planets.
Description:
CSTAR observed robotically at Dome A (Antartica) from 2008 March 4
until 2008 August 8, taking an image with each telescope whenever it
was dark enough to do so. The exposure time was changed from 20s to
30s on April 4.
